/* the followin is the complete file that takes care
of the visual stuff
* i've kept the menu and menu items global, i did look
at the handlers and they
* do return true but i cant understand that how does
exapanding and compressing
* make them visible again.
* plz do tell me of any other bugs if you find them
and thanx again for your help :) */
