I typed in 'Multiple Monitor Support' into the search box and clicked on the search button, got me the answer I was after.
The answer was that there is a monitor button that one clicks to swap between monitors, I had not seen the button when I was remote controlling that computer before so I asked the question here before I did a search.
Yes, but what if you have two monitors at work, for example, and two monitors at home, and you want to use both on logmein at the same time, just like you do at work (not toggling between them)? I have the mac version, but used it in Fusion and see it also doesn't work with Vista there.
I set the multiple monitors on host (the computer before me) to horizontal span - single screen, then switch the client view to full screen and select All displays (or something similar) in the display section of LogMeIn toolbar.
