To reproduce: Open a compose/reply window. Focus on main CM window. Click on Quick Search's Extended Information button to open the Information panel. Closing the information panel via the CM-provided Close button works fine; but if closed via the window's close button, raising the previously opened compose window will not restore keyboard/mouse focus to the compose window -- it stays on the main window. To restore proper focus, either kill CM and restart (nothing lost); or, re-open the Information panel and re-close it with the CM Close button.
Sometimes, only killing CM will help; not re-opening/closing Info panel. Haven't found what triggers the difference between the 2 restore methods in original report.
I keep checking as I work... had a couple of segfaults for which --debug and gdb haven't helped. segfaults happened when closing the compose window as the very first action after restarting CM following the kill.
