That's much more sensible. I'll do that. Thanks.

which seems somewhat ludicrous. There must be a smarter way?

Yes. What I usually do is add a category to NSView that returns the first superview that is of a certain class, like this: (warning - written in Mail, untested, you know the rest)

- (id)firstSuperviewOfClass:(Class)aClass
{
	id aSuperview = [self superview];

	while (aSuperview != nil)
	{
		if ([aSuperview isMemberOfClass:aClass])
		{
			break;
		}
		aSuperview = [aSuperview superview];
	}
	return aSuperview;
}

Then you can pass in the browser's class and message the browser that way...
