sys.exit call from pythonw.exe gives error

[Jo Schambach]

I wrote a python GUI with tkInter and installed it on a windows machine
with the .pyw extension, so it will be executed from pythonw.exe instead
of python.exe, since I didn't want the console window to appear.
My application exits with a call to sys.exit. However, when this call is
executed under pythonw.exe I get an error popup window with the
following messeage:

---- start quote ----
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: C:\Python24\pythonw.exe

This application has requested the Runtime to terminate in an unusual way.
Please contact the application support team for more information
---- end quote ----

What am I doint wrong here?

Jo
