in reply to Perl Tkx module
Welcome to the monastery!
Can anyone please tell me whats missing?The code that fails. Without the code it's hard to tell what's the problem. Can you please provide us with code snippet that causes error? Also please read How do I post a question effectively?
Update: there's such thing as MainWindow when you're using Tk package, and that's not the same as Tkx, so perhaps you just mixed up these two packages.
