I've had similar problems with the delete key - it seems like it might be a window focus issue or something.

In addition, the new Morph Tool just flat out does not work consistantly (on my system, at least).  I still hadn't tracked it down, but it appears to be related to how close you have zoomed in to the model.  The result is, the tool highlighting just doesn't show up and the tool doesn't do anything when you click and drag.  It sometimes picks other objects (like the Ground), so I've tried hiding everything, but it still won't work in a lot of cases.

When this is happening, the cursor seems to flicker beteween the arrow and the cross-hair as I move it across the edit window.
