I have an 2011 iMac with 8GB ram running Lion 10.7.1 Installed fusion 4 and created a VM wiht windows 7. I allocated 3 GB of RAM to fusion figuring I had 5 GB of RAM for the iMac itself. Well... the only app running is Fusion and my free memory reaches zero and I hear the hard driving working on overtime. OK, what gives? I have been a big fan of Fusion in the past but version 4 eating all my memory is not acceptable. Suggestions?
