* 3/04/2001
*
* a nice little script to create exclusive, slide-out
* menus for ns4, ns6, mozilla, opera, ie4, ie5 on 
* mac and win32. I've got no linux or unix to test on but 
* it should(?) work... 
*
* Revised:
* - 08/29/2002 : added .hideAll()

// declared in the css disappeared with 31 menus, where 32 menus caused
// the d.write call to fail entirely.  When I changed
// it so that the style changes were accumulated into one string
// (then at the end that string was written into the document,
// so that document.write was only called once) this solved the problem.
