I have an NSScrollView with a custom NSView subclass in it (created from IB). It draws just fine, but if I set the content view to scroll to the top, then call the scroll view's reflectScrolledClipView: method, it performs the scroll, but doesn't show the contents of the view. I have to either scroll down slightly, or resize the window. I've tried setNeedsDisplay on the NSView subclass itself, the content view, the scroll view, and the document view, all to no effect. Is there something else I need to do?
