Application Error with wxPython

[DP]

This is (barely) related to a previous question I posted a few days
ago.


When I run -

from wxPython.wx import *
chooser = wxDirDialog(None)
if chooser.ShowModal() == wxID_OK:
	choice = chooser.GetPath()
	print choice
else:
	print "Cancelled"

(Yes, that is the whole program. For now) I get the expected directory
choice dialog and a printout of my choice on the console.


When I run - 

from wxPython.wx import *
chooser = wxFileDialog(None)
if chooser.ShowModal() == wxID_OK:
	choice = chooser.GetPath()
	print choice
else:
	print "Cancelled"

I get an "python.exe - Application Error: Memory at _____ could not be
read" etc. and the application closes.


The same thing happens if I try any of the other controls in place of
wxFileDialog, e.g., wxTextEntryDialog. I've tried number of different
combinations, basically variations of the above, but always get the
same result -- an application error.

I'm hoping someone on this list can tell me if they're getting the
same application error, or if I'm unique in this. If it's the former
case, what should I be doing different? And if it's the latter, that
this problem is unique to me, what can I do to fix it?

I'm using WinXP Pro. And all of the demo that came with wxPython runs
fine.

Thanks in advance.
