Control doesn't stay centered?

This is really a two-parter, I guess, depending on the answer to the first part.

The first question has to do with a control not staying centered in my window, even though I've done what I _thought_ should ensure it stays centered in the window. That is, in Interface Builder, I've dragged the item (an NSTextField) onto my window, used the alignment tools to center it, and then in the "Size" properties, enabled the exterior springs on all four sides of the control proxy in the Inspector.

Most of the time, this does in fact do what I expect it to do. As I resize the window, the NSTextField instance remains centered.

However, if I resize the window _and_ the window size winds up smaller than the NSTextField instance, the centering is lost. Specifically, if I resize the window so that its width is less than than the NSTextField's width, obscuring part of the NSTextField, then if I drag the window fast enough to make it wider again, the NSTextField winds up stuck against the right side of the window, entirely in view but not centered.

I can fix it by dragging the window size smaller again and then larger, but slowly enough. Then the NSTextField remains centered as I expect.

Question #1: am I just missing some setting in IB that controls this behavior? Or is this a bug?

Question #2: if it is a bug, is there any way for me to check whether it's a known bug before reporting it? I looked at the bug reporting web site, but didn't find anything to let me search other bugs other people have reported. Assuming this is a bug, it seems to incredibly easy to reproduce and so incredibly annoying, it's hard to imagine it hasn't already been reported. So I don't want to waste anyone's time reporting it again. But because it's so easy to reproduce and so annoying, I'd also hate to fail to report it when I should have.

What's the protocol on that sort of thing? Should I just report it and be done with it? Or is there some due-diligence I can do to avoid adding to the pile of work someone already has?

Thanks,
Pete
