Mouse pointer sticks when guest window has scrollbars

[Frank]

The mouse pointer will move freely but then stop at an arbitrary x or y point as if at the edge of the window, but it isn't. The pointer can eventually break through the invisible barrier by repeatedly banging the mouse pointer against it. The mouse pointer then moves freely until it soon hits another invisible vertical or horizontal barrier. This happens only when the window displaying the guest desktop is smaller than the guest desktop, i.e the window has scrollbars. When the guest desktop window is resized so that the scrollbars disappear, the mouse pointer issue disappears too.
