No, it behaves correctly. Your problem is that NSBrowser creates a scroll view
for each of it's columns and puts an instance of your view's class inside such
a scroll view. Therefore, the right (though a bit dirty) way is the following:

@implementation NSView (FindingMyBrowserAdditions)
// finds the nearest enclosing browser view and returns it
- (NSBrowser *) enclosingBrowser
{
  NSView * view;

  for (view = [self superview]; view != nil; view = [view superview])
    {
      if ([view isKindOfClass: [NSBrowser class]])
        {
          break;
        }
    }

  return (NSBrowser *) view;
}
