Clippings Shortcut No Longer Working

I have been using command-space-comma for my clippings shortcut for some time in OF1. When OF2 beta came out, I went into System Preference and set up the clippings shortcut, and it worked fine, up until a few days ago. My primary use is in Apple Mail. Now it is no longer working. I have reentered my shortcut via system preferences several time to no avail.

Any suggestions?
