I know this is probably a dumb question but I am a Parallels newbie and not exactly computer-savvy, so I just want to be sure... If I assign 256MB of memory to Windows XP, which I am running through Parallels, this memory is only taken from my Mac OS when Parallels and Windows are running, right? Am I correct to assume that if Parallels and Windows are closed or suspended I have available my full 1GB of memory that is installed on my iMac for use with my Mac applications? Thanks.
