Dusting off an N90s

Just picked up a used N90s, dusted it off, and mounted my trusty 50 1.8 D. Weird thing: I can adjust aperture with the dial just fine in P mode, but when I switch A it goes to f22 and stays there. I can unlock the aperture ring on the lens and work it that way, but no dice when I lock it back up.

So it works as expected in P, not in A...Any ideas? Thanks.

I may be mis-reading your post but I believe this is the way lenses are meant to work on your camera. You open them to their widest setting and let the camera then control the aperture.

When you turn to A mode, what is the aperture reading? And what's the chance that in A mode the command dial and the sub-command dial switch roles?

And I take it when you move the command dial to change the aperture nothing happens, right? And just to be sure, you have the lenses' aperture ring locked wide open, right?

Exactly. I've also tried it with a second lens and the behavior is the same. The lenses work fine on my D800 and N6006 in A-mode.
