HI,
Smashing work - I was sooo dissapointed with the G7 not handling raw. Anyway - installed the version (I know these are quite fluid builds) but my G7 (firmware v "I") now wont respond to the ON/OFF control on the top of the camera, to get work you need to activate through on button at the the back and then half depress the shutter. Not a big problem for me but you may want to know. Keep this up - it's massive!
