I'm running PSE9 on a imac 10.8.2
I'm not sure why but PSE has just started opening up when I turn the computer on. How do I change this prefernce?
It could be that you have Restore Windows turned on system preferences>General. If that's not it, go to system preferences>users and groups>your account>log in items and make sure it's not in there.
No that doesn't seem to have anything. But thanks.
