Ok, so I just reinstalled SUP6 on my Vista machine to see if it would fix the problem but it didn't.
So the problem is that on XP and other OS' when you drag to select something a box appears around the area which you dragged from and to. Well on my computer when I drag nothing comes up! So I can't really see what I've selected until i release my mouse.
Does anyone know why it's doing this and a fix for it?
Thanks.
