Intermittent problem.
Upon returning to computer and moving the mouse, Vista will take forever to 'wake up'
On occasion I've sat sliding the mouse for 2 to 4 minutes to wake it.

I wouldn't use sleep if I were you, it is quite notorious for causing problems with Windows PCs. I suggest you use Hibernate, which saves your session to the hard drive and then shuts down the PC. When you start the PC again, your session is restored.
