Slideshow Win 7

Came across this MS program in Win 7, thought pictures were nice, loaded.
Big mistake. Program quits at any given time, message comes up that program cannot be found.
If working the net, often program starts on its own. Occasionally I can hit space bar and go back to program on net. Just as often I have to close out, then go back online and reload site I was working.
Would not have expected this from a MS program.
Am deleting Slideshow. It is more hassle that it's worth.
