The extra little window from ThinkSync will be dealt with. It's convenient for testing for the developer, but it'll be going away. Please contact bharper@stardock.com about the sync issue.
For the Unable to load bitmaps bit, what's the date/time/size of your wbsrv.dll file? It should be 12/20/05 22:57 176,128 WbSrv.dll for the latest beta. If not, that's what's unhappy. Please uninstall, reboot, and reinstall the beta. Or leave the release 5.0 build on for now.
