The spin button just under the Start/Stop button will allow you to set the program priority for ShowTime.
The range in value is from minus 31 to plus 31. To set the program priority to it's lowest point, turn the spin button down to minus 31. To set it at it's highest, turn it up to 31. Normally you would want to run a program like this in the background at it's lowest priority so it would be unlikely that it would interfere with the running of any other program.
