ElectricTNT: What I meant is this: a few times, I have encountered a strange problem with the skinning library - the avast! window became "transparent to mouse" - so, when I clicked on it, the click went to the window below (or desktop, if there was no other window below). So, avast! could not be closed in an ordinary way (how, when you cannot control it?)
So, if you put any other window below the avast! one, isn't it the case?
Technical: Could you be a little more specific? Report files for the Simple User Interface? Default name of the report or changed? Latest avast! version?
