When I need to run a program that should use the "Tkinter" module (I'm running Tickle 8.4.4) I can only briefly see the widgets I've created -- then the IDE, and my application as well, vanish, quit with no alert, no warning, no nothing... However, when I use the Python Launcher (v2.3 by Jack Jansen) to launch that very same program, everything works okay. What's wrong with my installation?

This is an intrinsic shortcoming of the IDE. Actually, I would think that the "Run with commandline Python" option was designed to work around that shortcoming... Indeed (was it you or me who put it in?:-), but you lose debugging and introspection, so you're really only able to use the editor portion of the IDE. If I understand things correctly Idle has solved this issue, and allows you to run your program in a different process than the IDE but still allowing you to debug. At some point we should probably steal this code.

PyOXIDE supports this (debugging & introspection of "external" processes), using a scheme that looks much like Distributed Objects. It also doesn't use threads or anything funky (yet), though requires explicit handling on the external side (there's a debugging stub that does this when you launch as "remote" under PyOXIDE).

The goal was to be able to add that "nub" to an app that embedded python (say, a MMRPG that used Python as a scripting language) and then one can debug from PyOXIDE, though saddly that will require redoing stuff in PyOXIDE to use threads in strange and fearful ways...
