When I am in the arrange window and I want to open File -> New for a new arrange window Logic hangs. I try trash the plist and I try to start without plugins ... Still the same?? What to do??

Not sure what is going on there, but if you want a new arrange window (not a new project), you can hold down the COMMAND key and hit the number 1 on your keyboard and it will open a new arrange window. Is this what you're trying to do? Or do you mean you actually want to create a second project and have it open at the same time as your current project?

That is very strange. So you say it didn't do it on 9.1.6? Try this, create a new user account. Log into that user. Then try start up Logic, and see if it does the same thing. This will narrow it down if it is a user issue, or system issue.

Thank you Morry for you reply. Yes I want to create a new project because I am not ready with the current project but a have to record a new song. Command 1 give me a copy of my current project. ( I am bad in English sorry. Hope you understand my problem)

Thank you Gary! Yes, before 9.1.7 I dit not have this problem. Later I try to create a new account I report this later. Have a good day, Henny
