I just thought I'd try this myself. I normally use FireFox with no problems so this is the first time I've tried it with IE8 (straight out of the box) Build 8.0.6001.18813. As I never use it, no add ons are installed. EDIT: Sorry I have AI RoboForm installed.
I get the same result as gruant. Just thought I'd let you know. (This was on the WA Demo of PowerCMS by the way).
