In upgrading a Blackberry app from Curve to Storm, I found an issue in some cases of pushing a popupscreen. First of all, it needed to be a PopupScreen instance – Screen wasn’t working right.
B/c of that, I had to change the width/height type settings a bit.
But the real thing was that I needed to add a doPaint() call after pushing the screen. Weird.
I hope that sames someone else some time. 🙂
