I can't get the flash to operate in most scripts. It works normally outside <ALT>.
I tried two CHDK versions, 1.4.1 5097 and an earlier 1.4.1. You know the four scripts that come with CHDK? The flash works with the HDR script but none of the others. Also doesn't work with MDFB.
I tried "always flash" and "auto flash" without success. I also tried to override the flash in Enhanced Photo Operations / Auto Flash + & Manual Flash +.
I am sure the flash used to work in the MDFB script but I have not tried to use it (the flash) in the script for a couple years.
Help if you can,
