Control Alt Delete CAX on Winhows 7 When Locked

[ken gray]

I'm running a Win7 Pro install and when I lock it, it has a screen that sits at a "Press Control Alt Delete" screen before I can put in my password.
I've tried everything I can think of to get it to lock and then wait a few seconds and then pass a CAX so that the screen goes directly to the password field but can't seem to get it to work.

is this even possible?

thanks.
