v4.1.2 and previous: amplified OpenGL mouse movements

Host: System -- Dell E6510: 8GB, 1.7GHz Core i7 Q720; Win7 Pro SP1 x64 Graphics -- Nvidia NVS 3100M; Forceware v270.61 Mouse -- Microsoft USB IntelliMouse Optical; IntelliPoint v8.20.409.0 VirtualBox v4.1.2
Guests: Win7 Ultimate SP1 x64 with Guest Additions installed Win8 Developer Preview x64 with NO Guest Additions installed
When running the OpenGL program Celestia v1.6.1 which is available at http://sourceforge.net/projects/celestia/files/ dragging the mouse in its window with either or both mouse buttons held down seems to cause the application to receive many more mouse evemts than it should or to receive unrealistically large mouse motion values.
When the LMB is dragged, the selected object should move the same amount of distance that the mouse is dragged. Instead it "leaps off the screen"
When the RMB is dragged, the selected object should rotate smoothly. Instead it rotates by unpredictably large amounts.
When both buttons are held down simultaneously, the selected object should move at a moderate speed toward or away from the viewpoint. Instead it immediately becomes extremely close or invisibly distant.
Exactly the same symptoms are seen when running Celestia in both guests and whether or not 2D or 3D graphics acceleration is enabled.
These symptoms are not seen when running on the host.
I am attaching a zip file containing VirtualBox logs recorded while running Celestia under Win8.
