Thanks for this. What I should really do is hide the textarea until the editor initializes. I think that's what you're seeing.
As for the TinyMCE issues with Firefox 3.0.1 - Can you point me to references for that? If there is indeed an issue, I need to make an update a high priority.
Just as an aside; It's a common misconception that java = javascript = jscript. Just for reference (im making big generalizations)..
java = full blown language which is compiled into applications and run in a virtual machine. Java applets run within browsers, but is not the same as the 'javascript' you hear about people writing for their websites.
javascript = a scripting language based on java which is basically interpreted as it's called/used.
jscript = microsoft's take on javascript. has differences with the ecma spec for javascript.
