The bug is triggered when trying to display a sheet on a popover window, so even if I capture error presentation I would still have to present a modal alert of some kind. I was hoping the API would do that for me gracefully, but I was apparently wrong. I could give it a try and see if it behaves better. >> I suspect that the tab key event is somehow not being handled and is passed >> up the responder chain to something that doesn't like it so beeps. > This seems likely. > You could try just handling this event yourself within the responder chain. > > I find that using XSViewController improves the whole NSView + responder > chain experience. I do force insert my view controller into the responder chain, although really just to capture -cancelOperation calls so I can dismiss popovers with the ESC key. Perhaps this is the problem. I will look up that alley as well. Thanks, Keary Suska Esoteritech, Inc.
