flash objects cause entire browser to blink.

An instructor here recently upgraded her laptop to Windows 7 64-bit. The laptop is an HP tx2-1275dx (a Touch Smart PC). Shortly after install was complete, she installed flash. This is where the problems started. She uses Internet Explorer (32-bit since flash doesn't work with 64bit yet as far as I know) and any page that she opens that has a flash video in it causes the entire browser to blink. This is made worse when she moves the mouse around. I have tried uninstalling and reinstalling Flash 10 to no avail. So we decided to install Google Chrome which also has us install Flash for it and it works just fine on flash objects. So it appears to be the IE install of Flash that is having the issue. I have Windows 7 here at work as well and Flash 10 works fine. Any thoughts? Any other info needed?
