I am using Parallels 6.0.11992 and Windows 7. I am running this on an intel iMac 10.6.6. I have a time capsule that is running time machine: this is connected to the iMac via Ethernet. My network is Shared Network. I keep getting my Mac going to sleep suddenly, forcing me to wake it up via touching the keyboard or mouse. It is really irritating. I sometimes get a little pop-up message saying another device (or something like that) is using your IP address. Is this a fair conclusion to believe that the Parallels network is fighting the Mac network? Is there anything I can do? Thanks Jim
