I'm a virtual newbie to Parallels (used it a long time ago but haven't used it for years). I have an iMac with 16GB RAM and want to allocate 8GB RAM, but Parallels is auto configured to 2GB. I've read the article 113649 which instructs to shut down the virtual machine then change the memory, but when I close Windows the configure option is no longer available. What am I doing wrong?
