I moved the IR543 about 1" backwards from its current
location and it no longer hangs up??? I can repeat this
by moving it forward again and it starts to hang up again.
I had a similar problem several years ago. The problem only cropped up in the afternoons. The problem was the sun was shining on the IR543. :)
