Using KDE 4.2.1-3.FC10 on Fedora 10/x86_64. Sometimes after pressing Alt-Tab to switch tasks the Alt key gets stuck down. That is to say every X client application connected to the X server behaves as if the Alt key is still pressed, even though it physically isn't. If I kill kded4 from a text console the problem disappears. If I then restart kded4 and the Alt-Tab functionality is restored, but the problem may happen again after some time. The problem doesn't occur every time I Alt-Tab but occurs maybe once an hour. This problem started to occur within the last few weeks after an update to the latest KDE from kde-testing (so probably since 4.2.1). Regards, Chris
