The mouse cursor doesn't show on the screen when Xplane is running. The mouse is working, the cursor just doesn't show. If I press the windows key to open the start menu the cursor shows up, even over the xplane screen. When I move the cursor to a box and click it the selected action takes place but the start screen disappears and so does the cursor. I can't find any mouse settings that make any difference. It works fine on all other programs including FS X.
