Diagram Window gets small everytime I save a Vi.

[LVNinja]

When I save a Vi, and close the diagram window, when I switch back to diagram (CTRL-E) it appears very small. 

Is this some kind of configuration ?

Thanks, i now found out that LabVIEW has had zoom functionality for a year😀.

If i zoom my diagram window (Ctrl-+), save, closes diagram window, opens diagram window (Ctrl-E) it appeares in the size it was before i closed it.
If i closes the VI and opens it again the diagram wiindow appears in the original size.

I do not know whats your problem, but some questions.

How long have you had this problem?

LabVIEW version?
What happens if you press Ctrl-0

What is your display resolution and screen size?

How do you get your diagram window to be "big" again?
