Can't get 40D ISO back up to 3200

I think I pressed something and I can't get the ISO to move all the way up? Any idea?

go into your menu and turn ISO expansion back on in the custom functions

Or another idea,
If you enable Highlight tone priority (C.FnII.3) which I did, you lose ISO 100, 125, 160, & 3200(H) . When I turned off Highlight tone priority all the ISO's magically reappeared.

no lucl yet... i cleared camera settings and that didn't help either

Hey is highlight tone priority a good custom function to always have on if one doesnt use 3200 or the under 200 isos?

They (Canon) say it may cause a slight increase in shadow noise. It will probably depend on ISO and the nature of the dark elements in the picture. Experiment to find out if the trade off is acceptable.
