KDE menu question

This is something I've noticed for a while (over several versions of KDE)... and it's finally bugging me enough to ask about it. When I add an application that adds things to the KMenu, sometimes they don't show up until after a restart of KDE. Case in point. I've installed CrossOver Office (in SuSE9.0), and Office2000... and the Windows Applications menu item doesn't show up. If I open the menu editor, it's there in the editor, and if I restart KDE it will probably show up... maybe. What gives? Why do some things show up immediately in the KMenu, and others never do? Is there soem way I've missed to force a reload of the KMenu without a restart of KDE (logout/login.. whatever)? C.
