Yes, the people walking around during conversations was really annoying.
Another annoying thing about conversations was how they would repeat certain phrases that didn't need repeating. One example I can think of is the Outcast leader on Taris whom I can't think of his name right now. Anyway you're talking to him and you say you want to ask him some questions. He then says, "Ask your questions upworlder...". The first time you want to ask a question, that's fine, but what about the third or fourth time in the same conversation?
