PowerPoint slideshow freezes when using other programs! Help!

At work I set up a computer with dual monitors. One of the monitors is a tv that we want nothing except a powerpoint presentation on it. So I created the powerpoint, ran the slideshow on the tv and minimized it on the other monitor. Works great, unless I open other programs on the pc then the slideshow freezes on the tv! If I open anything, ms paint, firefox, any window or program the slideshow freezes until the program is minimized. Then it continues. How do I get around this?

apparently this is because the slideshow is run in full screen. If I go to "set up slide show" and run by an individual window then all is fine but then I have borders. This is frustrating.

If you do anything to disrupt the full screen, the PP show stops - even if you only right click on the screen. Does the same on my system.

What you could do is a Video capture of the PP Show and play that with the media player. I have done that quite often. Here is an example: Power Point color fading on Vimeo
