I just tried something else.
When you attack a non hostile NPC, he usually say something like "ok, you want to fight". Then you click "end" and the battle begin.
If you switch on another character before you click "end" with the one engaged in the dialog, you can attack the NPC until he die while he's stuck because you haven't clicked "end".
I agree that it "CAN" make sense in some situation but not without any limitations. I really think that it would be way more interresting with rules rather than a system totally uncontrolled.
Well, in Multiplayer this is something that makes sense since you can't have everyone be frozen just because one person is talking.
Why couldn't everyone spotted enter the dialog or enter turn based mode rather than being able to act like if the world was totally frozen ?
