Hmm, I will try that once I have a new LCD (Mine died 2 days ago so I can't use my PC until the new one arrives tomorrow).

Its possible that is the problem, as it doesn't seem to occur until i've swapped to 2 or more clones. I do always make sure when using the swap feature to not touch anything until the background window becomes the foreground and gets resized. I find that if I move my mouse or something it can sometimes stop the entire process from completing.

Will try this in the next couple days and report back.
