The problem we discovered is when we do an "FOpen" command (File Open, which is as basic as it gets in Window commands), we found - depending on the computer - that editing the Singer or Key fields in the Playlist, which triggers the regeneration of the Singers Names Display (an HTM file) to be added to the Show Display.
As often as 1 out of 2, and as infrequent as 1 out of 30 times, Windows FOpen would return a "0". This says the file is not found.
Huh??????????????? 
30 times it finds it and the next time - all done within 5 minutes - it doesn't?
Senseless!!!!!!!!!!!!!! 
We also have a report from a lady that after testing this several times has proven that 2 messages in the Marquee won't cause crashing, but 3 will crash within a 3 hour show.
The FOpen code is used in opening the marquee .htm file also, so our fix for the first has also been applied to the second. We should have feedback by Saturday.
Still, not bad for 232 overall changes made from 4.32 to 5.00.
