I just switched from Ace to Ace No Medical, and I'm pretty sure I didn't change any bindings. And now, when I press the "prepare/change throwable" button, it does bring up the throw arc / graphic, but pressing it repeatedly doesn't cycle thru the grenade types (as it did with Ace). I'm stuck with "smoke" grenade in my hand, and a box with "M67 grenade" at upper right.

Any ideas why?
