I have an issue with opening Mathematica notebook. I'm using Student version of Mathematica 12.0 on Windows 10. When I initiate the Mathematica or create a new document from the start page, it opens without any problems. But when I click to open the already existing notebook, it seems to be opening off the screen with only a little bit of it visible on the far right edge (attached screenshot). I can't move it at all. Have you ever encountered this problem?

Yes, I have encountered this problem very often. For me, the reason is that I have 2 screens on my desktop pc and when I save a notebook which is on the second screen and open this notebook later, e.g. on my MacBook, then it happens that the notebook window has coordinates outside my Mac screen-area.

The solution is simple: Assuming testme.nb is your notebook (you need to include the path as well), then you can do:

nb = NotebookOpen["testme.nb"];
SetOptions[nb, WindowMargins -> {{0, 0}, {0, 0}}]

and it should jump to the upper left corner of your screen.


In Windows, it is simpler to right-click the Mathematica icon on the taskbar, select the notebook, which is still off-screen, then hit Win-LeftArrow (or similar combinations) which will dock the notebook on the left of the visible screen.
