thanks a lot for all the energy you put on this problem, really!
First I want to say that we found out in different forums that many persons has the same problem. One also describes the same procedure that you told me about "Audio to score". It seems to be a bug in Logic 9. I wonder why I started to experiment it only after updating to 9.1.3.
Logic 9 has been now completely reinstalled and updated to 9.1 on the big computer (on MacBook I still have 9.1.3, to see if there is some difference.
An important thing: in Transform window, if I drug up or down the numbers of "transpose" Logic crashes. Some other people experimented this in forums. One has to select and enter the number or select and scroll with the mouse wheel. In this way it seems to work. BUT it never happened before to me.
Coming to your points:
1- Yes, this occurred (I still have to work a while now to see what happens) in any project. Even starting from a New blank template.
2- I will do the new user account but I before I want to try if it works how it is now. As soon as the technician will come back we'll do it.
I feel kind of shocked because in few days I've had a HD Broken, reinstall the all operative system and now this last joy. So let me rest a moment.
3 - We found very strange that Logic doesn't have an Uninstall. We have had really some problem to clean the Mac to all Logic files and when we reinstalled Logic still some parts couldn't be reinstalled (mainstage, compressor...) because still present somewhere! A real chaos! And to do it was a real expert person, not me.
Could Apple do something about it?
Ok, I try go back at work now, if God helps me!!
As soon as I can add something I'll let you know.
Thanks a lot. And just let's wait a moment for the party!
