We are currently running DS v9 and OS v9 on Windows 7 but are getting ready to upgrade to OS v10. We are going to be purchasing a new computer when we make the upgrade and was wondering which Windows version (Vista, Windows 7 etc) OS v10 runs best on. In the past we've had machine glitches that we were told was due to the upgraded software (related to the version of Windows we were running). Any advice or things to consider is appreciated.
