Thanks for all of the help. I was able to track down the hanging quick upload problem with your help.
Now if anyone is having a bad path issue on Linux, please let me know... maybe it was a misinterpritation of the hanging issue, which turned out to be associated with KFM.
I'm going to try to get a new build sent out to you all tonight with all of your suggestions and bugs fixed. Thanks again for all the help.
I don't think there will be much we can do about the actual FCKeditor functionality like table editing in IE8 until they release a new version (if)... We are using the latest one available in 2.x and will need a massive overhaul to support v3.x, and that will have to wait for HTML editor v3... but still feel free to report any issues at all and we can look into them as best we can.
