Re: What is the deal with the Flash Pro error mesdsage "Unable to save the document as . . . " "Please try saving to a different filename or to a different location."

i agree with you.  this happens more often with flash than any other app.

it appears to be caused by the air debugger or the air debug launcher which fails to terminate properly.  to remedy, open your activity monitor (mac) or task manager>processes (win) and terminate the debug launcher to see if that solves the problem.  if not close the air debugger.
