Several times during the last two weeks I've been running two instances of RS Logix5000, each with a separate file opened so that I can refer back to an older version program. One instance (the one with the new program V16) will be online, the other with the old version (V13) is offline. Several times one instance or the other will crash (both have crashed). A few minutes ago, I got a blue screen with both instances offline. No problems at all when I have only one instance running.
I haven't tried upgrading the old V13 file (its in use in another PLC), I guess I could make a backup and upgrade it.
