We're listing Windows 2000 SP2 as a supported platform in our System Requirements page: http://www.openoffice.org/dev_docs/source/sys_reqs_aoo34.html
But has anyone actually tested with Windows 2000? I tried to install Windows 2000, but I can't even get the ISO image from MSDN. They pulled it years ago, apparently as part of a legal settlement related to Java: http://msdn.microsoft.com/en-us/subscriptions/ff723773.aspx Unless anyone is actually testing with Windows 2000, and we're willing to treat failures in Windows 2000 as ship blocking issues, I'd recommend that we stop listing it as a supported platform. -Rob
