I'm seeing some strange behaviour when you put items in the right column of the start menu and you have childitems in the left column.
The popup for the childitems of the left always sits at the top and if you're left column item is further down to the bottom, there is a disconnect between the two of them. Trying to move the mouse from the left column item to it's child items popup, closes the popup before you get there. When there are no items in the right column, the popup stays, but when you have items in the right column, they receive the focus, and it closes the popup.
To reproduce:
Create a new RadRibbonForm
Add 4 items to the StartMenuItems
Add 1 subitem to the last item of the StartMenuItems
Add 4 items to the StartMenuRightColumnItems
Now, when you hover over the last StartMenu item, you can't get to the child item.
