Hi pkinnane, thanks for the tips. I have noticed that P5 does seem to corrupt things more if I save in pz2. In fact I have had files saved that I could not later reopen. I have had less problems with pz3 in P5. What I have started doing, when I use P5, which truthfully is not real often, I keep running backups, sort like b1, b2, b3, and then one BB that is sort of the master copy of the current. After I get to about b9, I start over again with b1. As for tip 2, that does not seem to work for me. What has worked is either waiting and sometimes the problem clears itself up, and when that doesn't work, sometimes I can click on the P5 icon again on my desktop, like I am going to launch the program new, and that will sort of jump start it and get it working again. When all else fails, I give it the three finger salute and start over again - which happens a bit more often that I like.
