Prop program acting up

I wrote this code sothat when the button is pressed repeatedly the digit display on the LCD reads from 0 to 8 and repets the same sequence.The Green and Red LED
connected serially so that green LED lights up whem the digit is 0-4 and RED led lights up from 5-8.
I have the circuitconnected to a Parallax SchmartBoard.
The code works as intended with LCD displaying correctly but as soon as I disconnect the USB connection to the SchmartBoard the LCD display shows gibberish, when I reconnect and reset the SchmartBoard it works well.
In other words the code works well as long as the USB connection to the computer remains connected.
I have no clue what this issue is?
Needs some assistance.

See this thread's post #5 for the reason.
Duane,
I built the same circuit on a "Propeller Proto USB" board and ran the same code as before - Now it works well
irrespective of whether the USB is connected to the computer or not.
Thanks for you help
