Parallels has released Beta2 on their website today. Be sure to read the Release Notes before installing. They have several new features and improvements to speed, bug fixes, directx fixes, etc. Also check out the "Known Issues" on the release notes. Be sure to shutdown Parallels and do a complete uninstall with the Uninstaller provided in the package. My install on XP went perfectly with no hitches and no noticeable bugs so far. www.parallels.com/en/download/desktop/beta
