[wxPython-users] ScrolledMessageDialog error

[luisgustavo at petrobras.com.br]

In the program bellow the dialog works for 32 clicks if file contains 1000
lines,  4-5 if it contains 5000 lines, none if it contains 10000.
I believe this dlg is not intended for big strings, but maybe there is a
memory leak somewhere.

Thanks,
Luis

PS: "wxPython in Action" is a great work! Thanks again.

Please create a small runnable sample that shows the problem so we can
see exactly what you are trying to do.
