I have just installed Parallels 4 and Visa 64bit on my Mac. The Vista is running great and no problem except in the Configure settings on the VM, I cannot adjust the Memory allocation or video allocation or any of the machine specific settings. It shows me using only 1GB of Ram in an 8GB box. In the Prefernece settings on the Mac desktop I can see another Memory adjustment that is woking fine but has no control ove rthe VM systm. Any help would be great. New to the Parallels world and trying to make it work Thanks
