This happens in both drupal 5 and drupal 6, actually.

If you already have a nice menus set up, do the following to reproduce:

1) Find a child menu item with a menu description so that when you hover over the menu item, the value of the menu item's "title" attribute appears in the "tool tip" box. To really see this bug, this must be a child menu item, not a top-level menu item.

2) Hover over the menu item until this description appears.

3) As soon as the description appears, move your mouse a just a hair, and you will see that all flyout menus disappear. You have to wait until the "tool tip" disappears before you can move the mouse again if you want to keep the menu.

This seems like a bug inherent to the browser. Beyond removing the "title" attribute, not sure what might be done.

This is pretty much a show stopper and make this menu system unusable in my opinion.

Fixed typo in title.

I've experienced this as well. SimpleMenu has the same problem. It appears to be a browser issue, as I've only seen it in FF3. Something about the tooltip showing up triggers some kind of action that drops all JavaScript-powered menus.

UPDATE: I should note that I saw this happen with an older version of SimpleMenu. I haven't tried the newer versions.

Hrm, so it seems to be spreading to more browsers. #247904: Titles fouling nicemenus in Safari was a previous issue on this. I'm marking this a duplicate, please reopen that issue if you would like to submit a patch.
