I recently acquired a a2e body (recently as in this morning) and it has the odd problem of not changing modes, well it does but you have to put your whole thumb on the top and turn. As you may suspect this is a pain. My temporary fix is to duck tape the outer mode ring to the inner circular part so they move in sync, altho, this is not optimal when you turn the outer ring only you can hear the spring being weird.

Well any suggestions?
