Hi,
I just downloaded version 5.21 of the menu and while it fixed my opera problem, it changed the way my menu is drawn for the worse.
Previously, setting itemwidth="100%"; caused all the items to spread out across the menu to fill the whole width of the menu. Starting with 5.21, all of the extra width goes in the first menu item. You can see this on the top menu here:

Is there something I need to change to adapt to the new version?
