Mouse I-pointer and crosshair pointer disappears when using Guest Additions (Vista host, WinXP guest)

[Jake Catayoc]

I'm using Windows Vista as my host and Windows XP as my guest. When I'm using VirtualBox Guest Additions and mouse pointer integration is enabled, the regular mouse pointer appears ok, but when I move my mouse within the guest to a textbox, or to a window which is supposed to change into a crosshair pointer, the mouse pointer disappears on those areas. When I move out of the affected areas, the regular mouse pointer appears. The other mouse pointers, like the hand pointer when selecting a hyperlink, and the hourglass pointers appear fine.

When I disable the mouse pointer integration, all pointers are working perfectly. However, I'd like to have the mouse pointer integration enabled as I would have difficulty moving from an application in my host and an application running in the guest (I have to hit Right-Ctrl every time.)

Using the same VirtualBox version on a Linux (Ubuntu Jaunty) host and the same Windows XP guest, I did not experience this problem.
