 :::::::It was easyblock.js causing the conflict with User:Haza-w/Drop-down_menus gadget in user prefs.  I can live without EasyBlock, but I can't live without my user and page tabs.  Incidentally, when I added in most of the gadgets and JS that everyone had recommended I got tabs that went to the right of the screen beyond the edit window - and I got a horiz scroll bar in the firefox browser so I could actually even see them all ;)   "
