I have XP pro edition with the service pack. It's fairly stable too; little slow may be cuz I have so many programs installed in it. Comparing with new technology my pc is little old ... P4, 1.4Ghz & 512 RD ram. I think freezing up has lot to do with runtime environments and plug-ins. Maybe I have one or two of those, which is not suitable with Vue. Afterall you know, there are no such thing as "100% perfect". :)
