Hi, you may want to try this:
You may want to go to this site: http://www.adobe.com/software/flash/about/. Right click on the Flash logo, Settings,
then UNcheck the hardware acceleration in Display Settings.
See if that helps.
I had a similar problem with IE9 that went away with other browsers. It turned out I had recently updated the Adobe Flash Plalyer and this caused IE9 problems. The fix was to change an IE9 setting as follows in IE9 select "Tools/ Internet Options/ Advanced Tab" and then select the first option "Use software rendering instead of GPU rendering". Save and restart IE9.
Hope this helps.
