System Information
Ubuntu 13.10 64-bit
Intel Ironlake Mobile x86/MMX/SSE

Blender Version
2.69.10 f70d966

Short description of error
If a sub menu is opened and mouse scroll is used to select a menu item, moving the mouse (even a little movement) makes the sub menu to lose focus, and the parent menu gain focus instead.

In this video I access a sub menu and then change the selected item by scrolling. When I scroll with no moving the mouse, the selection works properly. If I move the mouse, immediately the sub menu is closed.

This is an annoying issue, because the scroll selection is intent to speed up the selection action, so right after selecting a sub menu and it opens, I start to scroll, but the mouse is still in moving by inertia. So the sub menu is closed right after to be opened.

Checked on this report,

There is a problem where moving the mouse can cause a state inbetween de-selecting one menu and re-selecting another.

If the wheel or arrow keys are pressed while in that state - the submenu closes and the parent menu gets the event.

I've increased the margin for checking mouse motion to 8px so this wont by accident. However if you intentionally wave the mouse while using the mousewheel or holding down an arrow key, its still possible to redo the bug.

Committed change:

IMHO its reasonable to expect the user not to wave the mouse around fast while using the wheel.

closing.

Thank you, @ideasman42

You're right, moving the mouse while using the wheel is not intentional, but an effect of inertia of moving to the new menu just few seconds before to start using the mouse wheel. So I think this solution will be enough.

But I just discover another way to trigger this bug. If you place the mouse cursor above a "separation line" of a child menu, and start to scroll, it will close the child menu and move focus to the parent menu, even without moving the mouse.

So maybe this bug can be relate to not having the cursor above a menu entry. I'm sorry for not had investigated enough this bug in the beginning.
