Broker Search
 

It seems this UI doesnt have the Clicking on the item name in the examine window working correctly for the broker searches.

You could normally click on the name and it would search for that name in the broker, instead it seems to search for Null (Nothing).

Is this a problem I'm having, or is the UI like this?

I don't use the 'full' DrumsUI, but I do use the standalone market window; and can't say I am having any difficulties with it like you are. Perhaps you are mistaking the result you are getting with simply more of a 'your search found nothing' result.
