Windows OSS Only For Administrators?

Torsten writes "We all know it: it is no good idea to run Windows with Adminstrator privileges all the time. But when you use a normal user account, many programs will not work properly. I have recently recognised that even open source software has difficulties with the Windows rights model. Openoffice will continue to ask for registration until an Administrator stops it. Firefox will not install new search plugins for normal users and will not even tell why. FlightGear starts the configuration screen, but only an Administrator can fly. Have the OpenSource developers problems adapting the windows right model? Or does nobody bother being Administrator?"
