Yep...and I have something to say! I got an old mouse that dosn't use a USB port then unplugged the mouse that did use a USB port and unplugged my IPod cable and guess what! When I ran blockland and moved the mouse...the game managed alot better although it was still a bit jerky...but its playable now! I do have a question though...is there a website that I can go to upgrade my USB ports?
