I get :Video Exent FX" in the corner of some kind of "trimmer" box, which is filled with the transparent text backgroud pattern of small white and gray blocks, instead of opening the usual box that has sliders for, say, "Brightness and Contrast". I do not know what I did to do this, but I can't finsh my project till I can correct this problem- I get this same "timeline trimmer-like" box when I should be getting the controls to make the title say something other than "SAMPLE TEXT"!

Please hekp me if you can.
