#1888 Hang after variable browser close

[High Performance Coder]

Reported by Amila Dissanayake

Thank you very much for your reply. Here are some additional details about the issue:

• Current Ravel Version: ravel-3.19.0-beta.6-arm64.dmg
(This is the latest version available for Apple Silicon.)
  Here’s what happens:

• I create Godley Tables and include variables such as Loans and Deposits with their initial conditions.

• Then, under the “Var” section, I click “Browser.”

Normally, a pop-up menu should appear showing all the variables, parents, integrals, etc.

However, in my case, even though all the variables are properly included in the Godley Tables, the Browsing pop-up menu is completely empty. Because of this, I’m unable to perform any simulation work.

Additionally, when I close the pop-up, a red “Waiting” bar appears, as if something is loading but nothing ever loads.

Correspondence copied from Patreon chat:

Thanks - yes I was able to reproduce this issue on both the 3.19 beta and the latest 3.18 release on MacOS. Conversely, this issue doesn't present when running the software on Linux. I'm not able to test this on Windows ATM.

Would it be possible for you to raise a bug report at https://sourceforge.net/p/minsky/tickets/ so this gets tracked and fixed.

Also, if possible, could you try earlier versions of Ravel to see if this is a regression

Maybe solved by moving browser functionality into an HTML window, as per https://sourceforge.net/p/minsky/features/233/

Hang appears to be fixed with a change to mutex handling suggested by Github Copilot.
