Hi,
Confirming.....
Clearing cache and cookies in FF doesn't solve the problem, it simply works for a single pass to get the toolbars and text box to show.
In looking at the page source, my first guess is....the IFRAME for the editor in that window is failing to load [consistently].
Shadows of darkness...why did it have to be an IFRAME? ROFL
I'm sure they'll figure it out.
