I think my issue is slightly different. The scroll bars never appear,
no matter how much overflow there might be. I generally don't have a
problem using table views as they seem to have some built-in mechanism
for notifying the scroll view that they are deeper than it is. I'm
trying to make my custom view do what table views are doing. I was
hoping to do it all in IB but it's looking like I'll have to do the
notifications programatically.

I may be wrong, but I came across similar scrollview behaviour in
Tiger. IIRC, I asked about it here on cocoa-dev and got back that
it was a known bug. As I say, not sure if this is still the case.
My workaround was to uncheck the 'has scroll bar' in IB, then, in my
case:
id scrollview = [[tableView superview] superview];
[scrollview setHasVerticalScroller:YES];
[scrollview display];
The behaviour I was getting in my table view was that if you/the
user selected a visible row, then arrow keyed down, it would
continue past the bottom of the window but no (vertical) scroll bar
would show and you couldn't see what was actually selected.
HTH,
