Well, I have just tried to fix it in a virtualbox Ubuntu (running in Windows XP). Although it can run but I can only 0.2-0.5 FPS. Too slow for me to debug. But I don’t have a spare machine to run a native Linux at this moment.
If you click something on the “Functions” listbox, the framework will immediately set the focus to the Panda window. I am not sure if it causes the problem you described here.
