Installed Windows 7 to my Parallels 5.0 setup earlier tonight. Everything went well, but for some strange reason, I'm unable to allocate more than 1Gb of RAM to Windows. My Mac has 4gigs of RAM and I would ideally like to allocate 2gigs to my Windows VM (I won't be using it that often) but when I open the Memory pane of the Virtual Machine Configuration panel, I'm unable to move the slider in either direction, nor am I able to manually adjust the RAM value. Sure this can't be right. Can anyone help?
