Latest update works great, thank you!

I have two 24" monitors and have this setup:
One is landscape and sits right in front like a single monitor would, the other is portrait and on the right side. The portrait monitor is used for all the Windows 7 gadgets for monitoring the weather, cpu usage, network, email alerts, etc. It also has the web browser up for quickly looking up info while I'm playing a game (in windowed mode) on the landscape monitor.

When I launch photoshop or lightroom, I use the right monitor for the main program and the one in the center for the resulting modified picture. Adobe has built in support for dual monitors so you can have all your toolbars and library on the non-photo realistic screen.

X-Fi runs very well on Windows 7 64 bit. I know it's Creative but ... perhaps a more modern Creative architecture like the x-fi could solve your problems. I'm running an X-Fi Elite Pro with Win7/64.    5.1 surround sound with both blu-ray movies and the latest games.
