Hi all,
Have a computer built up to do music editing that has an Nvidia FX 5500 AGP video card in it with dual displays. This setup works great with Sonic 4 software and every other application we can throw at it. Problem arose when we loaded Adobe Premiere on the computer to do some on location video editing. Premiere will open, but one screen (B Screen) goes blank....but...if you drag the window over to the B screen....the A screen goes blank and the B screen magically appears. We're stumped here, and to make matters even better...Nvidia doesn't support their video cards...something to keep in mind when you're buying that next Matrox product....oops....was that a bad thing to say? Thanks in advance guys...

You will find you will get a better response ,if you take the time to fill in your 'public profile' the specs of your machine and the OS+version can help diagnose problems easier.
Did you check Adobe's site for any conflicts ,since the problem started with that software?

How did you set it up ? DualView ? TwinView ?

Would it be possible to get a screenshot of your display settings ?

You can upload the image to the Gallery or to a place like ImageShack.
