Cross-Browser DynMenu JavaScript

Hi there. Attached you will find a short Javascript coding for a horizontal dynamic menu (categories cascading with mouse-over effect) designed to navigate an extranet. This menu works fine on PCs (both Netscape or MS Explorer) but comes out with a severe bug on Mac (tested with MS Explorer 5 on iMac : sub-categories are invisible). I would like someone to please review this code and amend it to make it cross-browser and cross-platform (Win, Mac, Linux, MS Explorer, Netscape Navigator, Opera). Thanks. ## Deliverables 1) Complete source code of all work done. ## Platform Windows XP, 2000, ME, 98, 95 Mac OS Linux All 3+ versions of Explorer and Netscape, Opera
