Leopard has plenty of bugs at the moment. I can not get my music server to run. I used migration assistant after doing a clean install to get things working better. A lot of people are getting blue screens of death. I to was one that had that problem, but the clean install fixed that. After the running Migration Assistant some of the my applications from my old system are not compatible and will not run. Photoshop 7.0 is not working after the Migration, and I'm sure other ones are not also. I will try to reinstall and see if that works.
