I seem to have lost my transport module.  Oops, I did find it, but it seems to be a drop down thing and I can't seem to drag it to a new postion on the screen.  Is there a reset for the default screen? I could really use one right now.

Never mind, I right clicked on it and reset the control bar to default and everything is OK again.
 
However, I discovered a new problem when Exporting audio to a new file.  The first time it produces a 0 byte file.  When I do it again using the same untouched settings, it seems to work.  This takes two times to get one mixdown.  Is this a bug? User error? Incorrect strategy, Number One?
