Thanks for the advice on the gloves popping off. On the second part I am putting them on with my hand through the ring first. I then slide my hand into the glove. When I try to lock them in, they just won't grab. Sometimes I can get one of tabs to lock but never both. I have an email out to sitech so we will see if they can add any thoughts to my issues.
OK, been there; If you bend the "ears" out a little they will stay out. If they are bent in, they will stay there and not work. They seem to tolerate the bending well, although I did manage to break one off on my car door window-frame just getting out of the car. I'm going to post the emergency-save-a-dive fix (which I may convert to permanantly) in a separate post which may require pictures.
