Submenus not working in a frame in Safari

This appears to be an bug in the recent version of Safari (1.2.2).

Sometimes, if a menu is loaded into a frame in Safari, the submenus will not show when activated.

The page works normally when it is not presented in a frame.

Solution:

You can fix it by setting the "Scrolling" value of the frame that contains the menu page to "Auto" instead of "no".
