Excel 2007 Crashes when Scrolling

I've been using Excel 2007 for a while now, and while I generally like the 'ribbon' and new layout, I've had a chronic issue with crashes.

When I scroll using my ThinkPad TrackPoint scroll feature, Excel crashes. For quite a while I assumed this was a driver/hardware issue related to the TrackPoint driver. Today I discovered a coworker has the same issue, using the scroll wheel on his mouse.

After doing a bit of Googling, it seems others are seeing this as well. Unfortunately, I haven't found a solution yet. I can't believe a feature as basic as this is causing widespread crashes without a fix. If anyone has a solution, please let me know.
