LogicX Piano roll - Link - Arrange

Hi,

I just upgraded logic 10.4.1 to 10.4.4 and of course I found a ridiculous problem: I use to be able to select a region in the arrange window, see it on the piano roll, change track on the arrange while continue seeing the region on the piano roll, and play on the new track. Very useful.

Now, if I select a region in the arrange, it automatically changes to the same track, so I can't play in another instrument. Uncheck the Link button doesn't resolve this, since will not change the region displayed in the piano roll window.

Any ideas?

Thank you very much
