I used to use VMD without a problem on my Mac (late 2013 MBPr with
Yosemite), then suddenly the display in OpenGL display panel disappeared. I
get the "Unable to simultaneously satisfy constraints" error. When I load a
molecule, the program behaves as the molecule is loaded, however there is
no display in the screen.

I tried a few things with no avail. I would appreciate any help. Thanks in
advance. Here is the full report:

Set the NSUserDefault
NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have
-[NSWindow visualizeConstraints:] automatically called when this happens.
And/or, break on objc_exception_throw to catch this in the debugger.
