When panning and zooming in the program default Beep is sounded, why and how to avoid?
This default beep sound is played because the user has issued a command before the previous command was completed by the program. Hence the default Beep sound is played.
Option #1: Ignore it and continue working.
Option #2: Slow down while panning and zooming to give the computer time to finish rendering the entire image before initiating the next command.
Option #3: Turn off the computer default beep sound, see youtube video for instructions
