Lost dual display while adding singers disk to playlist

[Skybird]

Have used Hoster 4 times at shows. The second display goes out in the middle of the show. This always happens when I'm adding a song from a singers disk to the database, while a singer is already singing. Then the 2nd display disappears. I shut down Hoster, restart the laptop & it keeps telling me I only have 1 display. I click on extended desktop, restart the laptop and it just won't hold. I did that for 2 hours while running my show on a regular karaoke machine. At the end of the show, I shut down my laptop, unplugged & replugged in the video cable & all worked. This happened in 3 shows, all while "adding to playlist" from a singer's disk while someone is singing at the same time.
On the 4th try, I only played songs already on the laptop - and played all singer's disks from my separate player. This time the display stayed.
So.......... how can I add from their disk while someone is sinigng without losing my second display? It's a pain going back and forth between 2 machines because so many singers bring in their own disks.

have you updated your video drivers from thier manufacturer ?

Think this is how to reply to Post???
I thought I updated everything before installing Hoster, but maybe not. I'll check on video drivers. Thanks.

the 2 things i would do is make sure windows updates are current, including custom and express, then i would re-install hoster.

are you running windows Sp2 ?

YES, I did all that BEFORE installing Hoster a little more than a month ago. Can I just check to see if video drivers need updating? I hate to uninstall & reinstall - that's such a pain!

yes

you need to go to the manufacturer for video updates.

Everything on my laptop was updated BEFORE I installed Hoster, so I knew that was not the problem. Thought it only happened when I trying adding songs from disks while another song was playing at the same time; however, it also happened in the middle of a show for no apparent reason. I tried unplugging the S-video cable in and out and that only temporarily fixed the problem. Then, I removed & replaced the electrical cord & that fixed it & the video came up immediately.
My last 3 shows didn't have that problem, but I also read the Manual again & it definitely says to have the TV plugged & TURNED ON, BEFORE turning on the computer - that way the computer recognizes the fact that there is a second display. Otherwise, it always defaults back to a single display so that when you plug the TV afterwards, it may show for a while, but then it disappears. I don't understand either, but having the TVs on BEFORE booting up has fixed the problem.
It would be nice if you could just PLAY a singer's disk in Hoster without having to ADD it to the Playlist by uploading it first. It doesn't seem like a long time unless you have to do it 20-40 times during a night and then have to add the same songs week after week. For this reason, it's still easier to carry a separate CDG player, but then All singers will not appear in the Playlist because you can't add a singer's name unless you have a song to go with it.
I wish we could add a person's name to the list and then add the song they want to sing at a later time. Sometimes they say Add me to the list, but they don't know what they want to sing until later. That happens a lot!
