David, I also use 6.1.2. I run into this problem but not quite 20 seconds long. Usually only as much as 5 seconds. However the ONLY time AC has been crashing on me is exactly when crystal reports starts running. Blam! About one in fifty times to one in one hundred times, I'm cruising along no problem, then print a lab, crystal reports starts....crash. Damn I don't like that.
