Version: (using KDE 4.1.3) Installed from: SuSE RPMs panel can cover plasma toolbox The toolbox placement should be adjusted in such way (here moved up) so it is 100% visible. see ss.
Created attachment 28617 [details] toolbox
Qt: 4.4.3 KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2)) kdelibs svn rev. 895869 / kdebase svn rev. 895869 In KDE4.2svn plasmoids are uppered if they placed above a panel. However, sometimes, the applet handle isn't fully displayed
Qt: 4.5.0 KDE: 4.2.70 (KDE 4.2.70 (KDE 4.3 >= 20090415)) Plasma Workspace: 0.3 I can confirm this too. If we try to move widgets near panel, it automatically moves away so that at least expand and configure buttons of applet handle are accessible but sometimes applet handle hides behind panel such that we can't access button to delete widget.
as mentioned the applet will move itself. i'm not sure if that can even be fixed (without restricting the placement of the applets near the panel). please reopen this bug if it is still a issue for you with the latest kde version (4.3 or 4.4 beta 1)
I'm on 4.4 beta1 and the widgets automatically move out of panel so the problem is no longer there. I think we can close this bug.
