Now THAT is why I LOVE forums!
It didn't work for me, but I never would have found that myself. After it didn't work I tried removing the entire base plate to see what was going on under there. Didn't do much but poke around very gently. Nothing seemed loose from a superficial view. Didn't want to dig deeper as I don't want KEH to reject my return.
Thanks for your help, though! Wish it would have worked!
