just a thought: have you tried creating a new user account?
then:
“DiskWarrior costs around 100 bucks, thats quite a lot for “trying”
I don’t think it would help with your problem (but could be wrong) but in any case DW is a software to have in any professional toolbox. It has saved me several times more than its cost me.
Also, have a look at digital rebelion’s software. Some is free and helps in running a clean fcp (Pref Manager) and they also have some fcp centric diagnostic software.
hope this helps,
Patrice
