I'm using MS Excel 2003 on Windows 7. I get animation lag anytime I open or close the Insert Function Wizard. I'm running on an ATI Radeon HD 4870 with the latest drivers (Catalyst 10.8 -- 2010/08/27). Excel is fully updated (as far as I can tell).
My Excel setting for
Options (Tab) -->
Menu animations (Last item) is set to
(System Default). I'm not sure if this has any effect for the Insert Function Wizard. Windows 7 Visual Effects are set to everything checked except for
Save taskbar thumbnail previews.
Here's a video to better describe what I'm seeing: http://www.youtube.com/watch?v=G6CvyclBcB0
It doesn't quite show off the effect that I'm seeing that well. It appears more slide-showy with the progressively smaller rectangular borders being much more distinct. Unfortunately screenshots don't appear to be able to pickup on the effect. So that video is as good as it gets.
I've Google'd around for this problem and have only found others that have experienced this problem on Windows XP but have not found a fix.
