>I always use 10uF tantalum.

Thanks. I see the d/s does say > 4.7uF. I had been told that a 1uF
MMC would be OK so I hadn't looked it up before

Tacking on a 22uF SMT tantalum doesn't seem to have made a
difference to normal operation.

However, this morning ...... What happens with reset now is that
when the button is released, the LCD fills up with white blocks. It's
a white-on-blue 16x2. This is with or without the added cap

So, it's displaying 'Ready' on line 1. The button is released and white
blocks appear after the 'y', to the end of that line. There's a pause,
presumably they are filling up to the 40 characters of line 1 in the LCD
controller, then they appear at line 2. It takes probably 1/2 second
for them to fill line 2 with 16 blocks. Eventually they wrap-around
and over-write the 'Ready'. A similar thing happens no matter what
is displayed. White blocks fill the screen from the last print position

Current still drops from 74 to 32mA. I'd put this down to the dsPIC
perhaps going to sleep or idling

I foresee a day not doing what I was hoping to be doing

Joe
