Hi Joe,
Thanks for pointing out this issue, I do not use IE as my main browser so I had not noticed this. Obviously a large percent of my visitors use IE so this was not giving a very good demo experience for my products if the editor wasn't working. So, I'm very glad to find out about this and fix it. Its always something with IE, I mean hardly ever do Firefox upgrades mess anything up but with IE some things get fixed and some things get broken with each new version.
I was able to work around it by switching the YUI version from 2.7.0 back down to 2.6.0, you can do the same by adding this to your user.config:
<add key="GoogleCDNYUIVersion" value="2.6.0" />
The templates and styles are only available in FCKeditor, it was low hanging fruit to integrate into FCKeditor, it will be a much taller order to come up with something for each editor and it is not a high priority for me at the moment. As it is, FCKeditor is the only one with built in image browse and upload as well, its the only editor I use and I recommend it above the others.
Best,
Joe
