was just testing something and decided to activate iso-real and iso-market in misc setting, but on screen i see:
I-R:0
I-M:0
whatever iso I choose.
tried on s95 and s110 with chdk 1.5.1
What is happening when you observe these values? What ISO mode, what shooting mode, are you shooting or in half press?
Generally speaking, I'd expect these values to only update on half press after get_shooting() goes true, and to display the prior value outside of half press. On startup, showing zero is normal.
