[Typo3] RTE htmlArea: contentCSS for IE?

[Namuk Tscholak]

Hi,

to change content with RTE with the firefox-browser also I switched to 
htmlArea and removed the standard RTE. For firefox it works fine now but 
in IE I dont have my CSS-definitions in the drop-down-box for 
blockstyle. There ar only the two default entries(standard, undefined) 
visible.

Any suggestions?

best regards
