Re: View disappears with NSViewAnimation

Yeah, I thought of that, but I don't think this is the problem.

The view itself (right now) is a custom view that draws its own 
background. It has 2 "springs" set in IB -- one to resize vertically 
and another to have a flexible outer right side (the side with the 
"content" view). Everything else is static. And I've tried removing 
the settings with no beneficial effect.
