Thanks Andrew

A similar problem also appears to exist with some Intel chipsets too.  I 
tried the release candidate on my Acer note book with similar results.  
Haven't had an opportunity to try the final release yet but will comment 
agin when I have if the problem still exists.

Have a good day all
