Pythonwin-wxPython

[ratze]

Hi Everyone,

I am relatively new to using Python on Windows NT and hence using
Pythonwin. I have a question that  I can't figure out myself.

My  problem is that when I am developing a wxPython application
everytime the the start of my app fails due to an exception I cannot
start it again and get 'Only 1 wxApp per process!'. How do I get around
this??
And by the way, is there any possibility to set the default path in the
open dialog?

Thanks in advance!
