Its a common problem and many people ask about it from time to time and many times they dont get very good or the right answers on how to fix it. I had this problem myself so i decided to ask some of the experts, or at least i consider them to be. I asked over at Neowin Here is what i got told, and yes it worked. Go to your Control Panel Click the System icon/link Click on the Advanced tab Click the Performance button Find "Use drop shadows on desktop icons" near the bottom of the list and make sure it is Checked Thanks k22 for this. It really helped me out and im sure it will help others
yeah, it's not that much, just takes a few extra seconds, not bad. i have it on my comp like that, and it goes fine...
