Broken MainWindow form in swinglabs-demos
Assuming this is the same problem--can you check the MainWindow class
in -demos? Got the same problem that I had a few weeks ago, form
version is 1.3 which isn't valid for NB 4.1. I can't open the current
version of this class in NB4.1.
I wanted to add a title attribute to the demo class so our MainWindow
can have a title.
