Hello Carl and Melanie,

Carl>>I would guess it might be related to resolution. The pbp manual says thet the minimum delay for lets say a 4 MHz resonator to your pic is about 24 micro seconds....so when you ask for less...you are asking for too short of a pause....switching to a 20 MHz resonator should increase your resolution down to 3 micro seconds. <<

Thanks a million both of you. I guess I was assuming too much <g>. I knew there had to be something going on... I was up too late last night working on a stupid project... thank goodness there is not a time limit. <g>
