Just today, I upgraded from 7.x-1.11-beta6 to 7.x-1.11-beta8, and now, in certain browsers, my drop-down menus no longer work – you can still click the main links, but sublinks don't appear when you mouse over (or single-click in iOS). In Chrome, everything is fine. But in Safari and Firefox, nothing happens when you mouse over the menu items (or click on them on an iPad).
This isn't an issue on the demo site (and, therefore, likely isn't an issue for fresh installs), but it seems like it could be an issue for updated versions of older installs. I tried replacing all of my CSS files with those from the most recent release, but that had no effect. Do you have any advice?
