Version: onbekend (using 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2)) "release 3.1", KDE:KDE4:UNSTABLE:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (i686) release 2.6.27.7-9-pae When the job notification popup is dragged from the panel, it appears as normal window first. if the mouse cursor moves too fast (outside the window), the applet won't be dragged. It only seams to happen when the window is dragged over a crowded desktop. An empty desktop seams to be responsive enough so this problem never occurs. I temporary have compositing disabled atm.
On a related note, when resizing a job applet at the desktop, it will reset itself again to a previous size (or even refuse to cooperate with resizing).
