IE9 crashes when user clicks on toolbar dropdowns

[Rick]

The problem occurs in IE9. I am able to replicate it on 3 out of 5 computers. 2 of the problem computers are Win7-64Bit. One problem computer is Win2008R2-64Bit.

Basically, clicking the toolbar dropdowns ('Styles', 'Format', 'Font', 'FontSize') will work the first time you click them. Clicking them a second time, will cause IE to crash.

I can't replicate this on the cdeditor site, however, I can replicate it everywhere else (multiple servers).
