Quote - I'm use Pro 2014, can't remember when that feature was added. Have you tried resizing by clicking and dragging on the end of the scroll bar itself? That's how it works in the graph palettes.

No, nothing. I can change the size of the window, but not the keyframes in it, and the graph pallette doesn't seem to have that feature in it, either. It's maddening because I did SOMETHING that made it that way a couple days ago, but can't replicate it.
