Mouse cursor appears when hiding AutoDrive HUD

[damnedsky]

If I have the mouse cursor hidden and use the shortcut keys to hide the AutoDrive HUD, the cursor appears and I no longer have control of the camera to look around. I think it's a toggle and it doesn't take into consideration the presence of the HUD.
Best way to reproduce this: start you map and hide the AutoDrive HUD directly from the keyboard without touching the mouse.
