I just got a new laptop (Dell D820) with the Intel Centrino Duo 2Ghz & 945 chipset (2GB RAM, 7200 RPM SATA HDD), and some VM's that I was using on another machine are acting up a bit. They boot and run just fine, but at times, they will go unresponsive (can move the mouse around, but clicks do nothing). I run my VM's though Invirtus' VM Optimizer and installed SpeedSwitchXP and made sure my CPU was set to run at max performance... both the VM guest drive & my host drive are defraggged... ideas? I'm running Virtual PC 2004 SP1 (v5.3.582.27) and I've installed the hibernation hotfix (KB#909095). I tried running the fix for the Centrino 915 chipset (KB#899525), but after rebooting, my situation was even worse. -AC [MVP MCMS] [URL="http://www.andrewconnell.co"]www.andrewconnell.co[/URL]
