The same thing happened to me with my 17" Samsung LCD, I believe it was even the same type of bug! I too waited for the bug to die off screen but instead, the bug decided to lay his grave in the dead centre, right at eye level. Now whenever friends use my screen they instictually attempt to swipe it away. What do I say to them when they ask about it? "Well, I was playing this game called Bugdom - it crashed really bad one day and left one of the bugs behind". Gets 'em every time.
