Giving up on Lion
So after 2 weeks of battle I am going back to SL.
I have a MBP with NVIDIA cards on it so presumably part of my problems have been down to the NVDIA drivers being wrong - but I can't find out what exact problems that causes.
I also am aware that many years of upgrading OSX has accumulated a lot of stuff in my System folder that restoring from a time machine backup or using migration assistant or whatever doesn't clear out.
So I am installing SL fresh and reinstalling my applications from fresh and not restoring the system from a back up. I hope that, once the NVIDIA issue is sorted out that I can go back to Lion, but in 25 years of owning and working on Macs never had to do this before.....
