When I drag a MAT file from Windows Explorer into any of the Matlab panes (Command Window, Workspace, Variable Browser, etc, etc) the mouse cursor changes from the normal Arrow to a Violation symbol (black circle with a line through it).
This behavior did NOT happen a few days ago, but, all of a sudden, does occur.
I'm using Matlab R2015b, 64 bit, on a Windows 10 machine.
No new software has been installed onto my computer from the time Matlab worked properly until the time that it stopped working properly.
What is the fix? And what caused this problem to begin with?
