Hi Chicken Vindalu,
That’s a nice, spicy dish!!
I have run into similar problems when working with certain items. What I had was that the Javascript used in the editor seemed to clobber some of the other Javascript that was operating with menus and so on.
I don’t have an easy answer, because the editor "takes over". Maybe if you have another browser, you can have it open in another window to see what’s "really happening". I develop in Firefox and sometimes have the dreaded IE6 open in another window, for instance.
Maybe somebody will have a better idea.
Namaste,
S
