My understanding of it is ALL buttons.
So that when you call popup button "somebutton"
0 is the correct setting. Go figure.

A file menu that contains a list of scripts in a folder, a list of 3D 
poseable scriptable model, a list of importable models, a list of level 
folders which contain scripts and models, and throw in a list of 
folders which contain textures and WHAM you have menuMode bug.

I don't know for sure. I would guess a single menu at least thats how i 
found the bug.

			lots of lines  each

I think it came out to like 1600 lines or so total. It was weird I ran 
dynamic tests
with lots and lots of submenus and nothing went wrong, sometimes,
It was truly baffling, because IDE instability wasn't instantly 
apparent, and once that instability occured
it usually ended up after I touched a menu Button with just 4 lines in 
it, so I spent forever trouble
shooting stuff that wasn't actually the cause of the trouble.

Right now my filemenu has 488 items in it (not all submenus mind you), 
so far no trouble. <knock on wood>
