Yep, I did know about this "bug" or "feature". Its due to the way style sheets are added by the theme, IE basically is being persnickety. You will need to turn the compressor on to do any IE testing b/c this is a subtheme so we are also pulling in stylesheets from Zen as well. 31 sheets I believe is where it gets cut off.

hi

this is a IE bug.

just use a module like this one:

http://drupal.org/project/unlimited_css

another one does almost the same:
http://drupal.org/project/ie_css_optimizer

but i prefer unlimited_css.

good luck

you enable css agreggation in core as well in administer -> performance which combines all css files into a singular file.

Its called "CSS Optimization" not aggregation.

Thats what the field set it called, yes. What is being done (the process itself) is that the multiple files are aggregated into one file.

For those who run into this thread (it's #1 in google for related searched) yes, this bug is still prevalent in ie9. Lame.
