the monitor flashing occasionally?
Interesting - that sounds more like hardware than windows...never seen that on any vista machine i've used- and i've used many now.

Thanks for the info Hengis, I think I will wait until the final release comes out before I update. I don't like the fact that this is a time limeted release that will expire on June 30. Good luck to those who take the plunge. Let us know how it performs. It would be interesting to get some feedback on those who are using RC1
