Suddenly the Proclaim system is not recognizing that a 2nd monitor is attached. I've tried it with both my 2nd monitor at home and the projector at church. While the computer itself recognizes the attached monitor, the software will not. Please assist.

I am using OS X El Capitan.

Thanks in advance!
