Quartus II v15 (small) bug?

[Altera_Forum]

After installing new Quartus II v 15 I came up with following problem:  

- normally, when I try to open a project file (let's call it test1.v) which is already open in Quartus window, it won't open but will get focus, - let's now assume that I close a Quartus with this file open. When I reopen Quartus and project and than try to open test1.v file, it won't get focus, but will be opened again (as a second file).  It's not very intuitive and was changed (why?) comparing to older Quartus versions. Is there something that can be done with it?

Hi, just to clarify if the test1.v file still open while you had closed the Quartus ii software which meant the test1.v file was opened using other tools?

No other tools are opened. Maybe some illustrations will help to explain what I am talking about: 

- before I close Quartus II software I have following files open: http://i.imgur.com/w8qnpoo.png If I double click on "test1.v" in Project Navigator, this file will get focus in the main window. - after I close Quartus II software and reopen project, both files seen on image above are still open. But if I double click on "test1.v" in Project Navigator, this file will open one more time: http://i.imgur.com/fhjrhvx.png So it'll be open twice in the main window, as shown on the image.

What OS that you were using? It might be a bug that need to be fix.
