clearInterval(menu)
...but IE's error messages points to
menu = setInterval("ChangeHeight(1)", 30)
I'm at a loss what to do. My debugger in IE isn't working. All works perfectly in Firefox.
Except, re-clicking on the button whilst the menu is mid-slide screws things - in FireFox, everything gets out of sync, and in IE movement gets faster and faster every time you click. Great fun (for the first and perhaps second time) but a pain in the ar$e. I've tried to get rid of the button's OnClick property, and reinstate it once everything has stopped, but this didn't seem to work. (Those lines commented out).
Any help would be much appreciated,
