Windows 7 often eats touch events on desktop host

I've searched existing tickets and forum threads but haven't found any mention of this problem.
When running VirtualBox on a Windows 7 host with a touch screen, it seems that Windows is often eating "touch" events (especially if they are touch/drag events) and processing them into "back" and "forward" gestures -- as indicated by the icon that Windows displays at the location of the touch. Whether or not this happens appears to be related to how long the initial touch is before you move your finger on the screen.
This happens even with mouse integration enabled, and effectively prevents many touch/drag events from getting posted to the guest, or presumably even seen by VirtualBox.
I would think that in this mode (mouse integration enabled), the VirtualBox GUI should tell the Windows host to NOT interpret/process any touch events in the VirtualBox guest window, but just pass them through unmodified (and ideally sooner) to VirtualBox so they can be passed onto the guest.
Longer-term, it would be great if VirtualBox could pass multiple touch events through from any host to any guest, since Mac OS X, Windows 7 and Ubuntu 10.10 all support multi-touch now.
