Well, I sprung the $50 for DesktopX after checking out the website.  It worked great last night.  I had to tweak a few settings for my dual monitor setup in Nvidia Desktop, but it worked.  Well, this morning I thought I'd boot up once before going to work to take a look at my new desktop, and now I get "The file format you passed DesktopX is not valid".  Now, only the wallpaper and startbar load.  What gives???  I've tried reloading different desktops and get the same error.  I understand there isn't that much support for dual monitors out there, but I was willing to start developing desktops for them.  I'm a bit dissappointed in this, anyone experience the same thing or find a work around??
