Kevin, > I was the one who listed he advice in the post you mentioned above. > I'm a bit hazy on the details, but I wonder, why do you run your app > from the command-line with a bash script instead of putting it in a > proper Mac application bundle? because the application is unix crossplatform - it runs on Solaris, Linux, IRIS, Cygwin etc. Setting environment variables etc. from a launch script is _very_ common in the unix world. And Mac OS X is, at its core, unix. Only on the Mac Tcl/Tk supplied with 10.5 do I have these problems. (Note that double-clicking the bash script still leads to the Terminal problem. Running from the command line is not required.) (I'm not creating red hat/fedora rpms or ubuntu/debian .deb packages either.) Unix users moving to the Mac expect programs launched by a shell script to be able to use the menubar properly. They can use the menus under Tcl/Tk on Cygwin and elsewhere, and expect to be able to use them on the Mac... and this worked under 10.4/Xcode. My take is that Tcl and Tk are cross-platform, and that Mac Tcl/Tk should behave as Tcl/Tk do on other platforms and on other unix variants. (I have a couple of crashes and hangs where Mac Tk doesn't, so I do have some other simple workarounds in my code - like don't make a listbox too big because the Mac will hang - just for Mac Tk, as well as the whole 'draw popup menus using 80s menu code because we can't use the menubar on the Mac under Leopard' workaround.) Does a later version of Mac Tk fix these menubar problems, reverting to the correct behaviour of the Tk that was supplied with Xcode for 10.4? Can someone please ensure that such a fix is included in a version of Tk supplied in future versions of XCode? http://ayam.sourceforge.net/download.html "This port will run very slow on most computers, due to implementation deficiencies in the Aqua port of Tk; please use the X11 version" - anyone have details? thanks, L.
