Mystery solved - it was the kernel and/or XFree 4.2.1. An update of both XFree86 from 4.2.1 to 4.4.0 and one from kernel 2.4.19 to 2.4.26 did the trick. Funny I should have been the only person to have experienced this. Regards Andreas ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde.
