When presenting a slide show and using Presenter mode on my laptop, the cursor sometimes disappears from the laptop and I am unable to get it back. I can (sometimes) see it on the screen that is displaying the slide show but am unable to get it back onto my laptop to control anything else, such as opening another program, for example to play music/sound, etc. I have tried moving the cursor to the left of the slide show screen hoping it comes back onto the laptop as (I believe) it used to do, but no more. The laptop is connected to several tv screens in our church.
