I've installed Fences on my laptop, wife's computer and my desktop. On all but my desktop it runs fine. On my desktop the fade in/out when I double click my desktop is not smooth. It's noticeably slow. It's not my computer spec's because it's the fastest of all 3 computers. It's an i7 920 with an NVidia 260 GTX. This is the only computer that has 3 monitors running on Windows 7 64-bit (the laptop runs Windows 7 32 bit). Any one knows what the problem could be?

Thanks,

Adrian
