I'm not very used to forums,so hopefully you guys can help me out.I just installed iPC on my computer and everything is working fine except for one problem.The problem is,when I drag a window somewhere,it just repeats itself or in other words,it mirrors itself.Take a look at the picture below.Is there a way I can fix this problem when I drag an application window to move it?

Dell Dimension 8300
iPC Mac OS X 10.5.5 Leopard VooDoo Kernel
2.63 GB DDR Ram
Intel Pentium 4
