Though I have the plugin installed, and working as far as I know, the downloading function still does not work. As you suggest, however, if I use the icon for direct "send to gps" then all works fine and the gc is added to the gps. Makes me happy!!! I will try to do the "pocket query" but it looks to be complicated at first glance.
As a consiquence my wife and I went out today and located 5 gcs, which we enjoyed very, very much. Thanks to all for your help.
That said--it should not be that difficult and the instructions in this regard are terrible for a novice.
