drag and drop of .mat files

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 am using Matlab R2013b, on a window 7.

Please help to solve this problem.

Is it possible that you very recently installed a windows update?

Yes, I think so.

This happened me too when I changed to compatibility options for mablab.exe file in ../bin/mablab.exe

I changed the setting to "Run as an administrator" and after that I cant drag any thing to matlab.

After I removed the check for that option, the dragging works again.
