I got another email from the guy at Kreg over the weekend. He
maintains they haven't had much trouble with the new screws - BUT they
are going back to their traditional square-drive screws.

I wonder if that means back to the non plated or back to strictly square
drive, or both. The plated screws used a combo Philips/Square drive head.

I got a little grief here a ways back for saying that I needed to put
modest pressure behind the bit in order to get it to stay in the hole.
I was (and am) using the plated dual-drive screws. I have a feeling
that the "dual-ness" may be part of the problem.

Hard to say but a worn bit will slip out if the bit is past it's prime. For
many many years I have used the combo screws, non, plated that McFeeley's
sells with out issue. For the more heavily plated bits that McFeeley's
sells they offer a special under sized bit. I would suspect the plating
giving more grief than the combo head style.
