Multiple Hoster Sessions

[tdproduction]

Greetings All.... I had a very strange situation mysteriously appear at my show last night. First a little background. I have been running Hoster now for several months and has run flawlessly until last night. I booted the computer as usual and deleted the left over entries in the song list from the last show. Then started entering the new requests. While arranging the entries in show order, hoster stopped responding. Now here is where things start getting weird. Pressed CTRL-ALT-DEL to end the task, and found 8 sessions of hoster running. Ended all the tasks and restarted hoster. Now all the new entries I entered in the play list is gone and the old entries from the previous show are now back again. I look in the task bar and there are now 6 sessions of hoster running. I ended the tasks again and the last session has the new playlist. Now I'm really stumped. Completely shutdown everything and reboot. Hoster came up with the new entries in the playlist. OK so now it's time to start the show. Very big night... Over 60 singers. About 2 hours in to the show, here we go again. Exact same thing happens. All the new entries disappear and the previous play list comes back and this time there are 4 sessions running. I begged forgiveness from the crowd and stopped everything to reboot the system. Most of the current playlist came back but I had to sort through and rekey in several requests. Made it through the rest of the night OK. Has anybody else seen this before? I have Hoster running on a P4 3.2 GHz rackmount PC with 512 MB ram, Windows 2000 Pro with the lastest SP's and Patches, 50 GB of free HD space and hoster is the only app installed. I doubt virus's would be a problem because this system is not on the internet. Again this has worked perfectly up to now.
