Video Problem at the show last night (Hoster 3.0)

[tymzend]

Hoster 3.0 gave me some heartburn last night.

I booted up the PC (XP Service Pack 2) and was getting ready to start the show. We started the first song, and the lyrics were not displaying on the singer's screen, nor the giant projection that we use for the crowd.

So, I rebooted the PC, and I noticed when it was booting up, the boot screen displayed on the other TV's just fine, but as soon as windows desktop showed up on my PC screen, the other TV's stopped displaying.

Then, I booted to my back-up hard drive (XP Service Pack 1 and Hoster 2.219), and everything worked fine.

Anybody have any ideas on why 3.0 with SP2 wouldn't display the graphics to the other TV's, but 2.219 and SP1 worked fine?

I did the Windows troubleshooter for extended desktops, and everything it suggested was already done.

The drivers are the same on both hard drives.

Am I missing a setting somewhere? Is there something that I should have changed for Hoster 3.0?

Thanks in advance for your help.
