When I hover my mouse over the network manager icon on a clean desktop with no window open the popup that appears is just over the systemtray which sits at the bottom. Kopete, Klipper and KMix display the pop-up in the top right corner.

Now when I start any application and give it the focus and move my mouse to the try all pop-ups from any tray icon are displayed where they should be.

Window does not have to be maximized.

Reproducible: Always

Steps to Reproduce:
1. Have a systray at the bottom on a naked desktop
2. Hover Mouse over tray icons, see where the popup appears
3. Start a Terminal maximize it
4. Hover Mouse over tray icons again see where the popups appear
Actual Results:  
Popup for some tray icons appear in the top right corner

Expected Results:  
All popups should appear in the bottom right corner right over the systray

Things that won't fix it.

1. Reinstalling all KDE 4.10 packages with pacman
2. Deleting the system tray and adding it again
3. Deleting the entire bottom panel and creating it again as standard panel

Additional Background:

I had a standard panel at the top once, because I wanted to try out the global menu. At one time I also had two panels [one with K-Menu, menubar-widigt and systray at the top and one for the window taskbar at the bottom (created a standard panel and removed everything but the window taskbar at the bottom)]. I dragged some of them around from time to time. I guess this must have confussed the hell out of the systray at one point. Can't remember exactly which panels I created in what order and which I dragged around etc.
