Thanks Colin and Brian for your info. I am aware that if some one wants to capture a screen, there are other ways besides the "Prt Scr" button. I believe that most of the clients that I have, probably wouldn't seek out alternative methods. I use the 'Don't allow' feature in Pict2exe purely as a deterrent or precaution. I know if someone really wants to copy my work they will find a way to do it. Just as an alarm on your car or house. If some one wants to steal the car or rob your house, they'll find a way to do it.
