Hi Costin, The A-D references are only connected to 100n decoupling capacitors and have no other external connections. I did try adding 47uF to each pin, but to no visible effect. The lockup time should be no problem, as the system sits in 'expose' mode for long periods after the registers are loaded, but I can check this. I will also check the Page 0 registers, as you suggest. I will mail you some screen shots of the effect. Thanks! Terry
