Hi!! This is just a theory.... Do you have "Think Pad" on your machine ? I've noticed there seems to be some kind of conflict with the WMP 11 and Think Pad caused by Vista SP1. I don't know if Superbills stuff will work, sounds great, your manufacturer hasn't solved the problem yet. Let us know how it works out... P.S.- I've heard of people going back to previous versions of Windows Microsoft Player (OLD) Maybe that, or another type player would work better.
