The main reason the program chokes while making a slideshow is that the photos are too large.
If you down-rez your photos to no larger than 1000x750 pixels in size, the program will work much more efficiently and be much less prone to crashing. (Photos directly from a digital camera can be 10 to 20 times that size!)
Thank you for the feedback. I re-sized all of my photos for the slideshow, which I'm sure helped a bit. However, it has not corrected my glitch problem. I'm thinking it may have something to do with the DEP system on Windows (Data Execution Prevention)..... where when my computer notices memory being used in an unusual way, it shuts down to save my files, etc.... I'm playing with it now in my control panel. Any other suggestions are greatly appreciated!~
When I have program closed due to DEP I have always had a warning message saying that DEP is closing the program... and then given the option to disable it for the program.
What format is your audio by the way... MP3 can sometimes make PE7 do funny things... best to convert to WAV. You could also try the Render and replace for your timeline (under Audio) this will do what it says, render your timeline and replace it with a WAV file.
