Multiple Displays

I have decided to connect a second display to my 27" iMac. The goal is to have Windows :mad: (through VM Ware Fusion) running on the alternate 20" Samsung display and leave the iMac for all the Mac stuff. I need Windows due to some Microsoft Applications (Access, Visio etc...)

Problem: If I open a full screen app (e.g. Mail) on the iMac, the second display goes into a new "desktop." I knew this would happen, but I was wondering if there was any way to disable spaces or more desktops on the second display. It would be fantastic no matter which space or application on the Mac I was using, the second monitor would always remain on the first space, using VM Ware Fusion.

I am running the latest version of Lion (10.7.3), and Windows 7 on the VM Ware Fusion (3.1.3). Please ask any questions that you might have.

This is one of the flaws in Lions's full screen thinking. It's meaningless for dual-screen user like myself too. I have an ACD 24" attached to iMac 27" but never use fullscreen mode now.
Need to check with ML if there is any change.

I really hope that Apple fixes the Lion Full-Screen setup as well. It kills the multiple-monitor users. :mad:

The second I installed Lion I wanted to have a Full-Screen Safari window on my secondary display, and a Full-Screen iTunes window on my main. I was sadly disappointed when one of my monitors was filled with a grey-leather-type graphic, while the other had a full screen application window. I was so pissed!

Such an unbelievably counterproductive implementation on Apple's part. I really really really hope they give us multi-monitor users a fix this summer with OS 10.8.

Why would you want to run mail in full screen on an iMac's 1920x1080 screen anyhow ? :confused:
While I too question the utility of this particular use, Apple's full screen implementation is still sketchy. I wish there was a way to have Spaces operate separately per display, which would resolve these issues. I'm not sure exactly how they could implement that, though.
