Hi there,
I tried your DISKBOOT and found those things:
1) I set the camera to TV and select a shutter speed, for example 1/40.
Then I open the CHDK menu, and leave it again.
Now, the shutter speed is not 1/40 anymore, but 1/160.
Same happens with other shutter speeds, and happens also in M mode.
The ALT/S key in the original menu is set to the first option "Not Available".
2) The original histogram is enabled. I open the CHDK menu, and the histogram is now painted on top of the menu.
3) After leaving the CHDK menu, ALT is still enabled. Don't know if this is actually a bug, or if it is possible to disable that. I think it is a bit annoying.
Thank you anyway for the beta build!
cheers,
Benedikt
