Logic crashes when it tries to access other applications

Question

Hi - The problem I am about to describe has make Logic basically a useless application. It happens on Logic Pro 7 and on Logic Express 7 on my computer. I have tried it on other uses and the same thing happens. I have emptied caches, deleted preferences files for both express and pro, reinstalled both express and pro, and more, but still the problem persists in both applications. The problem: whenever Logic needs to use another application to do something, it crashes. Examples of these instances include, for when Logic tries to access the finder: saving songs, creating new songs, exporting midi files, freezing, and bouncing. Also, when I try to export to iTunes, Logic crashes. These are just a few of the instances and I'm sure there are other times I just haven't discovered yet. Everything I do in Logic that solely use logic, and doesn't access another application works like normal.
Has anybody heard of this? Any suggestions? Apple Care hasn't been able to help despite countless hours with them on the phone.
Thanks for any suggestions!

Answer 1

First of all repair disk permissions.
Then try a safe boot, i.e. start your Mac with the Shift key depressed until it's up then restart again normally.
Which version of Logic 7 do you own?
Do you have enough memory and disk space?
