Apple Logic Pro /LogicExpress Discussion

I am glad for you. Logic 9.1.1 is still hanging up on me. I opened it 
up fresh today. I did not have any audio or any virtual instruments at 
all. I just wrote a little midi sequence using the pencil tool - to use 
as a test file for a program I am writing to edit midi outside of 
Logic. So I export the file, and it hangs up for 10 minutes and I have 
to force quit. This happens 2-3 times an hour when using Logic. I have 
repaired permissions. I don't know what else to do. I have a dedicated 
hard drive that I just use for running Logic and there is no word 
processing, Photoshop, or excel. Just Music and Logic.
