Stephen Lee-Woolf it maybe that the virtual desktop program is not compatible,  Give Stardock Virtual Deskstop a try.  I use it and CursorFX with no problems.

Stardock's offering isn't bad, but it doesn't have anything like the flexibility of Dexpot (suh as the ability to run specific apps on entry and/or exit to/from particular desktops for instance)

Stephen Lee-Woolf, no SVD doesn't have a lot of options and features. 

The feature you mention is insteresting, not sure though how I would use it if at all.

Depends what you use your computer for.

For example, I play games from time to time and have one screen that I always use for that purpose. Dexpot is set so that when I enter that desktop all extraneous apps running in the systray that I don't need at that time (mail checkers, memory optimisers, download managers etc) are shut down to recover memory for the game and these are then reloaded automatically when I revert to one of the other desktops.

The potential, as they say, is limited only by your imagination.

That does sound like an option that would come in handy for lots of folks.  There will be those that say they have lots of memory for just that reason (so games and other programs won't be slowed down). 

Hmmm, wonder is Stardock is thinking about something like that?

Fair point about memory, but there are some games that get interrupted by notification of an incoming EMail, for instance. In my case I am working with a laptop so installing additional memory is neither cheap nor easy!
