You can manually update the scrollers position but there's a method on NSScrollView that will do it for you based on the content view's origin. - (void)reflectScrolledClipView:(NSClipView *)aClipView so, [[tableView enclosingScrollView] reflectScrolledClipView:[[tableView enclosingScrollView] contentView]] Ashley _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
