Problem: I have two menu buttons on my toolbar. If I have one menu open, I don't want the menu of the second button when I hover over that button. I set trackMenus to false on my toolbar to get it working as I want.

Bug: This worked fine in 6.2. After upgrading to 6.5 it no longer works. When a menu is shown, it will hide as soon as the mouse cursor is moved.

Expected Behaviour: The menu should not hide right away. If I move the mouse to the menu, the menu should remain on screen.
