Mocha AE "Layer Controls" popup window does not show up after I have returned to AE

I believe I am using Mocha AE properly, and I am saving after I complete my tracking.   I close Mocha AE and return to AE.   When I select "Create Track Data" the "Layer Controls" never shows up, although sometimes I do see the tracking points superimposed (when I add a Solid layer).    Is there some "allow popup" setting in AE that is the issue perhaps?   I can't figure out how to enable the popup.   Thanks for any suggestions.
