Okay then. Why don't you cowboy up to the task and answer it yourself? You are most welcome to look up the problem/answer on your own and post the solution. Not only do you learn something new, so do others. From what I've seen using reports on Windows, the engine stays there until you go manually cancel it (right-click, close). I don't care enough about the problem because it does not seem to affect anything. It seems like a "so what?" kind of problem, just another quirky thing about reports. Do you know something different about it?
