cfajaximport issues

After racking my brain for hours trying to figure out why this particular issue was occuring (only in Internet Explorer), it seems to be cfajaximport thats causing my problems.

The following page uses the cfajaximport tag to import the cfwindow tag for use:

http://www.middletowncityschools.com/site/index.cfm

Notice, if you roll over the menu item Schools and try and navigate through the menu, the menu will flicker and sometimes close completely.

However, if you go to:

http://www.middletowncityschools.com/site/index2.cfm

This page has ONLY the cfajaximport tag removed, and the menu works fine.

I also noticed that within Firefox's Error Console, the file /CFIDE/scripts/ajax/resources/ext/css/ext-all.css seems to be causing a slew of errors, such as:

Warning: Error in parsing value for property 'filter'. Declaration dropped.

What's the deal, Adobe?
