I just set up a simple class and a simple fla and .swf. Perhaps my preference settings are somehow not correct? I do see MTASC run in a command window, but then the error appears. Any other ideas? I see my post to osflash finally went through (after 12+ hours) so if you prefer, we can also move the discussion over there.
