I am a relative newcomer to JavaScript. I have been trying to implement the JS Anthology dropdown menu and have a couple of problems not covered in other posts or the book's errata page.

The first problem is that it crashes in IE5 (Win) as soon as you hover over any link in the menu system.

The second is that in IE7 (Win) when you navigate to a link via the menu and then return to the original page, the sub menu that you came from is still open.

Grateful for any assistance.
