Version: (using KDE 4.0.5) Installed from: RedHat RPMs OS: Linux If the Classic Menu widget is placed at the right-hand side of the panel, submenus sometimes overlap, making it impossible to retrace navigation. Moving the widget to the left cures the problem. This has been reported to Fedora in https://bugzilla.redhat.com/show_bug.cgi?id=443669
this is actually an upstream problem in Qt, where submenu sizes are calculated before being shown, but also before the aboutToShow signal is emitted. i have submitted it upstream to Trolltech.
