Bad news
It's there again :shock:
I fixed the part about closing a single file, but i forgot to make the change when a whole project gets closed. Anyway in case i die yadda yadda, the thing is that upon selection change in the open files tree, i call the currently active editor's focus() function. I suppose that something in between didn't get refreshed with the active editor changed.
I also call the open() function, in multiple windows, open just gives focus to the corresponding window. Mandrav, any insight on what could have changed between the interfaces?
