    Anyone have an idea what would cause this?

    I think I'll save Dave's memory test program in case any of my Props start acting strange.

    Static? As mentioned earlier all four (its a LQFP package SMT jobby) GND & VDD are connected and bypassed with 4 x 0.1uf's. Should be OK? Not had this problem before and used same schematic & similar layout. Its a four layer PCB BTW.

    Do you have any way of knowing whether the chip was always like this? Or did it work at first and then quit working correctly?

    no not really, this PCB and IC have been in existance for 2 or so years, and had mixed amount of usage. Explains some weirdness about some results though, last year here and there.

    Thanks for your help all, specially PhilPi and Dave Hein. :-)

    Im editing the app to avoid cog6, so all is not lost.
