I have another laptop that has ActivePerl on it and so I installed wxWidgets with PPM and it works (BTW, an amazingly easy installation). However, I installed wxGlade, but it didn't work. It seems there are two versions of Python installed and the wxGlade installation seemed to select one, while wxWidgets selected the other.
The important part is that wxWidgets worked for the examples I ran, so it seems to be OK.
In any event, I'll try some of the suggestions to try and get the Strawberry Perl version working.
OpSys: Win7 x64 Service Pack 1 Professional/Home Premium; Perl: Strawberry (v5.22.0)/ActiveState (v5.14.2)
