What I can't understand here is, with which of my opinions you disagree 
as one line below of my posting (you are responding to) I write: "I 
haven't said, that it is not suitable [for low-medium
size projects]." ...

By the way: why is it so hard to develop a wxPython application which 
runs with any wxPython version? Are the subsequent wxPython versions by 
definition not compatible or do only the quirks change from release to 
release being shifted between the problem zones?
