I am using parallels for autocad and set my virtual machine to have 1 of the 2 gig's of memory I've got on my mac. When I stop the virtual machine (windows) and completely close out/stop the parallels program, does the mac regain use of all of the 2 gig's of memory again? Or is 1 gig still set aside for the now inactive virtual machine? For some reason, my computer seems like it operates much slower. I have a hatred for everything PC and feel that it may be an autonomous response from my brain. But it brought about some curiosity of the memory situation... Thanks for any help!
