/* Dynamic menus v3.2.1 - menu_logic.js
*
*  Verified with: Mozilla 0.9.4, IE4, IE5, IE5.5, IE6, NN4.08+ 
*
*  Known issues: For Gecko (Mozilla, Netscape 6, etc.):
*	Mozilla 0.9.4 is the only gecko browser currently supported by this code.
*   All other gecko browsers simply don't have a complete enough DOM to do what's needed
*
*  Known issues: For IE5 (Under Windows 98)
*	Under windows 98, IE5 will intermittently not display the "dm_Image" item
*	Work-around: use IE4 code.  It's faster anyway.
