hi,

i installed 2.3 last week and now i got a debug message.
if i close a Dialog with ALT-F4 i receive this msg:

"..\msw\dialog.cpp(534): assert failed, wxDialog destroyed twice
Do you want to stop the program?
You can also choose [Cancel] to supress further warnings"

Please. Can someone tell me why i get this msg?

thx, reen

I had exactly the same error message when I upgraded. The problem was that I was calling wxDialog.Destroy() twice in succession, like this:

     dialog = MyDialog(parent, prompt)
     while true:
         result = dialog.ShowModal()
         if result == wxID_OK:
             result = dialog.getResult()
             dialog.Destroy()
              break
         else:
             result = -1
             break

     dialog.Destroy()
     return result

Earlier versions of wxPython didn't throw assertions, so this error went unnoticed. The new version is simply pointing out a problem that was in your code all along...

Hope this helps!
