Basically ive got it all set up just how i want it, except after it running for a while, i start to get phantom images of windows that i open appearing in the top left of my screen, such as a duplicate msn window or something, that disappears when you move a real window over it. When this happens, right clicking objectdock just produces a black text box instead of the correct options, my systemtray disappears and eventually just crashes with this error:

I then restart the application and everything is back to normal, if anyone could help it would be VERY appreciated. thanks
