Thanks mate,

yeap it was, put a delay in and runs like steam train, now need to workout what values to use as it is resonating as it steps (I am asuming this as it is very noisy and with others software (embbeded in 14Kb) it is quiet as.

Any one got any ideas on how to select the best values or is it a wild guess (their are about 32 pairs of values) :o(

Regards,

Kat.
