atmosworld I'm pretty sure your Mouse is supposed to disappear when not in use, and PowerPoint goes into SlideShow mode, for the purposes of uninterrupted presentations. The fact that the Arrow keys function indicate you should also be able to send an Esc command to exit the SlideShow if needed...
The trouble is when i press Esc - I still have no mouse - nothing. Even if I close Powerpoint using the keybaord shortcut keys I still have no mouse. The only way to get the mouse pointer back is to restart the computer. Logging off does not even bring the mouse back. I have full mouse control on everything else, everything works fine until I click the run/show in powerpoint and then it is lost.
atmosworld The next troubleshooting step I would perform is visiting your PC's manufacturer website in order to confirm that all your installed drivers are fully up to date. Afterwich, you'll be asked to reboot the PC, where you can test PPT behavior once again.
