Only a hint:
Hardware Acceleration" (GPU Rendering) is a new "feature" of IE9. :rolleyes:
If you want to disable the Hardware Acceleration feature in IE9, following trick will help:
1. Open IE9 and click on Tools icon. Now click on "Internet Options".
2. Go to "Advanced" tab and enable "Use software rendering instead of GPU rendering" option.
I used to get that response from the "options dialogue" on a computer running an ati card who's drivers were not in the OS mix.. I would investigate video driver issues on this.
