During a 2 hour session of working on a church program for the next day, the proclaim program shut down a minimum of 15 times. It had never shut down even once before since using this program. My team member had the same type problem on her computer which is also a PC. Last night at church, we ended up with a 3rd member bringing her computer. She had a Mac. and had no problems. Today I did a recovery, but one problem still exists: the media library stays down on the task bar and will not open up to the full screen so I may access it.. The file part does goes full screen, and I can use it. I have not been on the program long enough to see if it will shut down again but will get on it again soon to see.
