Zoom shrinking instead?

Question

howdy,
ok, so my cat walked across my keyboard recently, and for some reason i just can't figure, now when i hit the zoom shortcut key in aperture ("z"), my image gets smaller instead of zooming in. i've looked in preferences, in the menus, all around, but can't figure this one out.
any ideas? i feel like such a noob.
and before anyone asks, i'm sure i've got a large image to start with... it's a 10mp raw file. everything else seems fine, but hitting the "z" key makes the image shrink to about 2/3 size on the screen if in landscape, but if in portrait, it DOES zoom in a tiny bit (with the zoom navigation box showing almost full) . what am i doing wrong or not seeing in the menus.
it's amazing what i've learned from my cat.

Answer 1

Yea!
yes, my cat is fairly clever. she once swiped at the mouse while standing on the keyboard and made the finder screen zoom way in - i'd never seen that mode before, either. quite a teacher. let me know if you want her to come over.
many thanks for the quick answer, all is back in order. preview mode! can't think of when i'd ever use that, but at least i now know where it is!
