Since the new EAP builds I have big problems with the focus (again). I am using Ubuntu 9.04.
Everytime an exception occurs (red circle of death) I loose my focus (at least the keyboard events are no longer recieved from the editor).
Most of the time it is possible to fix that through opening the exceptions dialog and closing them again.
Working with two projects at a time is a nightmare - most of the time one projects does not accept any keyboard input...
