Find Related Messages in this Conversation in separate window

Is it possible to tell Outlook 2010 SP1 to display the results of "Find Related > Messages in this Conversation" in a separate window like the Advanced Search?  My Outlook 2010 SP1 won't do that and I can't find where to do that.  A co-worker just upgraded his Outlook 2010 to SP1 and by default this feature opens in a separate window now, whereas it didn't before.

Thanks in advance.
