Not sure what else to try - it works fine on mine, it will select ISO up to 3200 in normal mode and 1250 in HQ burst.
The fix in 1739 sorted out the overexposure issue for me.
Phil.
I got mine to go up to ISO800 in HQ mode, however there definitely seems to be a random element in how high it goes, as usually it does not exceed 400, sometimes it goes to 800, and very rarely I see it select 1250.
Also, though, if the max auto ISO is set to 3200 in the recent build, then why is it that yours only goes up to 1250, when there's one more step and a half still to go?
In ALT mode if you half press the shutter, and then press the left key (with the shutter half pressed) it will toggle zebra mode.
I've not had any instance of zebra being enabled when using bracketing.

I will do some tests to reliably reproduce this bug and ascertain in exactly what conditions in manifests itself & will report back.
LATER EDIT: ok so it seems that it activates Zebra mode whenever I half-press the shutter and then press the left key in order to switch to MF mode and set the focal distance to be the current AF value. This is just like you said above, except that, when I was doing that, I was *not* in Alt mode...
