I'll help you investigate why bumping Electron above version 37 breaks the canvas functionality on Windows. Let me start by gathering information about this repository and the specific changes in PR #636.I'll now search for issues related to Electron version upgrades and canvas rendering problems on Windows.Based on my investigation of the Minsky codebase and the PR that bumps Electron from 37.10.3 to 41.1.1, I can help you understand the likely cause of the canvas rendering issue on Windows.

Finally, this is the last update to the build environment for Intel Macs. When it fails, or Apple updates the build requirements again, we're going to have to drop Intel support. Hopefully that won't be for another 2-3 years.

Upgrade Intel Mac build environment to Monterey
-
Just finished :P. Took almost 3 weeks. In the end, I had to abandon the Virtual Machine approach. Virtual Machines were just too much of a nightmare with a Monterey guest system, so I will be building on the base system, and testing on the M2 system using Rosetta. Had extensive problems sorting out the code signing certificate, but Claude Sonnet eventually found the obscure configuration that needed to be flicked.
-
You're welcome! That approach strikes a great balance between robust security and cross-platform simplicity. Since you have control over the build pipeline, the detached signature method effectively treats your .dll, .dylib, and .so files as immutable data blobs, which is exactly what you want for stable verification. To wrap things up, here is a quick "cheat sheet" for your implementation: Build Pipeline (The Signer) Use OpenSSL to generate the signature during your CI/CD process: Bash Generate...

Just a brief note to say I've approved the PR, but I stuffed up the CI pipeline in generating a Windows release. I ran out of time yesterday trying to find out a solution. I'll merge the PR once master is green again. I going to have to create a new releases branch, so that fixes for quirks on particular platforms are quarantined in that and not break the build for the master branch. I've learned my lesson.

Good catch! I was wondering why this didn't bite us with Canvas event handling, but in that case, the PlotWidgets are manipulated through the Item interface, so it resolves correctly. But as you point out, with classdesc, the latest declaration trumps any earlier ones in the declaration stack, which means that the RenderNativeWindow intrerface (with the empty implementations) trumps the Item implementation. I think your proposed solution is the simplest, and probably most correct solution. Another...

Can't install Ravel

Yes, you are correct. This is on my laptop, so the last time I used it I must have done the Administrator install. I've just done the update and install with the latest beta, and there were no issues after I chose to install for just me.
-
Can't install Ravel
-
Clearly, you have installed Minsky as Administrator (All users). But when run it as a normal user, you won't have privileges to install the Ravel plugin in a system area. The most obvious solution is to uninstall "ravel" from the settings>apps dialog, then install it for just "current user". There is a new version out yesterday 3.24.0 that defaults to current user, and with no elevation, so you'd need to deliberately run the installer "as administrator" to install in a system location. 3.23.0 tried...

All I can say is that it works for me. For the sake of the exercise, I started with 3.21.0, clicked upgrade, clicked through all the prompts, and it ended up with 3.23.0 with Ravel 2.1.9-pro. For reference, I used Windows 11, 25H2 build 26200.7840. Maybe try again, in case it was a temporary network glitch. You will notice I have disabled "one-click" installation, as I have been told that some some anti-malware systems flag one-click NSIS installers as potential malware. Ideally I'd like to switch...

Lack of a debugger on Windows is a real problem, as this manifestation doesn't happen on Linux.

This looks like another deadlock situation. Switching to equations or phillips and back to wiring will reset any locked mutexes attached to the canvas. For reference, the version (from About box shown in videos) is 3.22.0, which is not the multithreaded version, so this is a little weird.

Movies. It turns out that I was actually moving stuff and placing things on the canvas, but the canvas didn't update until I opened Equations etc then went back to Wiring.

I waited 4 years for this to be featured 😂
-
Good one! I think it's more apt for the File menu--Edit is for things within a model. So a File-->Properties form on which the metadata can be edited would be good. That would include Author and a Short and Long Description, Keywords... Then if Windoze and the other Operating systems would display that in their Preview panes, it would overcome the current limitation of only being able to use the filename as an indicator of the file's contents. Data sources, etc., could be added later.

In closing #1785, I added a Edit>Description menu item. For discoverability, I also added your suggestion of File>Project Information. When you see this, let me know which menu item makes more sense. There is also Edit>Author for setting/updating your name.

I'll downrate this then. The plan is to reimplement this feature using an HTML table, but its not especially high priority. Maybe a job for Niels? And I'm not sure that it would solve the issue of screen recorders - are you recording the whole screen, or just a window? For Minsky recording, you'd need to record the whole screen, otherwise popups will not appear.

This may be because I was using screen recording software at the time, and this got in the way of the window. So not a major issue.

Calculation Error in Difference Operator

Took a bit to create a unit test that actually triggered this bug, so unit testing actually would have really caught this issue anyway. I did audit the codebase, and potentially flagged outerproduct, gather and index operators as affected by this "collateral damage" as well. I modified unit tests to try to trigger any bugs, so far they all passed, so as far as I know ATM, there are no issues with those operators. I also tried asking Github Copilot to audit the codebase as well, and it was completely...

This issue turns out to be collateral damage from the fix for https://sourceforge.net/p/minsky/tickets/1886/, which also brought in unordered index elements (for performance reasons). It would have been present in 3.21 beta, but because of the deadlock issue with Ravels, you didn't get to see that issue before it got pushed to production releases. The workaround for now is to downgrade to the latest 3.20 version. Originally, I thought to reinstate the version of civita used in 3.20, but then that...

Going to have to do a git bisect to figure out where this regression came in. No work has taken place around the difference operator for more than a year, Also funny that the difference operator is a plain delta, rather than delta^- like it is in 3.18.
