B) a oneliner with just "import wx" crashes hard with F5 in Pythonwin IDE
build 214/py2.6 - but not in build 212 (ntdll.dll)
AppName: pythonwin.exe AppVer: 2.6.214.0 ModName: ntdll.dll
ModVer: 5.1.2600.3520 Offset: 00044872
Code: 0xc015000f
Address: 0x7c954872
(wxpython 2.8.11.0 (msw-unicode))
Only after this patch below (passing the SendMessage by a direct python
call) it works again. (But with importing this oneliner file with Ctrl-I
the IDE still
crashes the same.)

Trying to run one GUI framework inside of another is a sure recipe for
disaster. Both will be trying to process messages, with race conditions
and memory conflicts galore. The short answer is "don't do that".
I'm doing this since adam and eve with wx, win32ui and similar. When there was/is a little problem I first try flatten it. e.g. join the OnIdle or message
translation. 2 or 3 things.
Have seen people which edit code, save, start the GUI app , bug, exit , edit,
start/test again ..
With dynamic Python I edit code while it runs, objects/windows live; fumble, try, autocomplete on the living objects, sys.exepthook postmortem pywin debugger, set
self=current_winthing_i_focus_on_for_a_while in the interactive , better autocompletion, Ctrl+Enter debug etc ... Even little reload code, exchange classes at runtime
on big apps with big status ... reboot after 30x or so.
Pythonwin is good therefor because of the joint thread. Its a feature not ...
I think there is simply something not as good as it was in build 212. It may
indicate/connect with deeper problems - like mentioned.
And the problem is just about "import wx" at F5/Ctrl-I time. reproducible. no GUI start at all so far. the crash is not when doing "import wx" first in interactive,
and then use F5 on a wx script... something with command handler status, GIL/reenter or so.
Would be happy about any idea.
Best
Robert
