Default Dual monitors and SLI on graphics cards

Just taken delivery of a new computer. I have opted for two graphics
cards(256 Mb Nvidia Geforce 7800 GTX) linked with SLI for hoped for
improvement in handling large 16 bit files in Photoshop, along with
the 2 Gig of RAM operating in Windows XP Home.
The problem I have discovered is that enabling the SLI facility
disables the dual monitor display, leaving only the primary monitor
showing anything on screen.I use the second monitor to view Photoshop
tools and dialog boxes.Disabling SLI restores both monitors. I would
like to have both if possible! Is there a workaround. Both monitors
are plugged into one of the graphics cards.
Out of interest, I have timed applying radial blur to a 100 Mb colour
file, and it takes about 34 secs with SLI both enabled and disabled.
If SLI is disabled, am I only working with one graphics card?
Many thanks
John
