Org menu dropdown disappears -- bug??

[rustom]

Some time back I found that the menu (drop-down) under python
'disappeared' ie clicking there did not show anything

Today I found the same thing happened for the org and tbl menus --
click there and nothing happens/shows.

Restarted emacs -Q and it was there.
Ok so something in my setup.

So tried
a My org specific setup (which is in a separate el-file) and no init
-- the menu is there
b My init but no org setups -- the menu has disappeared

Now I can of course hunt down which setup is the culprit. (Just have
to start and stop emacs about 30 times!!) But I was just wondering if
some tip/bug etc is already known in this regard

emacs version 23.1.1
org version 7.01trans
