(I posted this message in the wrong forum already so I'm reposting it here as it is a Mac question.) When I try to launch Windows XP Pro via Parallels Desktop 3.0 (build 4128) on a Mac Pro 266, 4GB RAM, 4 internal HDs, NVIDIA GeForce 7300 GT I get the following error message... "Parallels Desktop failed to allocate the specified amount of memory. Please restart Parallels Desktop and try again. To avoid this problem in the future choose from the menu: Parallels Desktop > Preferences. On the Memory tab select the "Enable virtual memory preallocation" option." This error just started for no apparent reason. If I restart my computer Windows launches and runs just fine (except for the failure when dragging single files from Windows to the Mac desktop.) I believe it is the case that this failure to launch occurs after my computer is put in sleep mode and then 'awaken.' Has anyone else seen this issue? Should my next troubleshooting step be a reinstall of Parallels? Thanks for any advice.
