Well... after twisting the button it started working fine so I decided to actually take it out for a spin last night instead of packing my OC gear.
It worked perfectly!!!! What a fun dive. I think I'm finally making friends with this thing.
Tim Thanks a bunch for the loaner bit, and MP thanks for the advice on
how to change the lens and buttons. You guys are great
.... anyone
who drinks boddingtons has got to know what's going on!
