We have a rather large menu that renders well in most browsers, with the exception of Firefox 2.0 on the Mac. You can see it here:
This menu works fine in Firefox 2.0 on the PC, and in Internet Explorer on the PC, and in Safari.
In Firefox 2.0 on the Mac, after a lengthy wait, we're getting an error message:
Warning: Unresponsive script
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
If you click 'continue', things just hang up for a while longer and then you get the error again. If you click 'stop script', the page and menu are displayed, but there are problems with the menu.
For example, multiple highlighted items appear on the menu, as you get rather deep into the menu - see 'fine art', 'by artist' and then view the various submenus by alphabet.
In addition, the menu remains displayed even after you move the mouse off of the menu. The only way to make it go away is to select something so as to go to a new page.
This code passed a validation, so I don't believe there any missing tags. Perhaps the menu is nested too deeply for Firefox? Is there a limit within UDM as to number of nested menus?
Thanks for taking a look and for any advice that you can offer.
