Window arrangement wierd

Well when i installed kdenlive on my Ubuntu 7.04 it looked nice and i liked it very much. However i started to play around a little with the window arrangement and it resulted in total chaos... now it looks like this

and i can't get it back as it used to be. Can anyone please help me? I tried to uninstall and reinstall it but that didn't work, the computer remembered my positions.

Known bug.
This is the docking bug.
To fix, remove kdenlive rc file.
Do not try to undock tools.

whats an rc file? And where is it placed?

Edit: I found the file in my /home/username/.kde/share/config and it worked perfectly
