Forums / Cotonti / Support / Markitup and IE8

is there a known issue with using MarkItUp! and IE8.  i've got 0.9.10 installed in 2 different hosts/databases and when using the MarkItUp! editor rather than CKEditor it doesnt work correctly.  all the bars/icons at the top of the edit box are unstyled and are just a list of the alt names...

I'm using MarkItUp because i prefer using bbcodes rather than html parsing.

thanks
