Thanks again Waterwingz and msl for your work, much appreciated.
what i do think is amazing is that I now see the canon superfine logo next to the L in the corner when the camera boots up in CHDK, last time I saw that logo was on my ixus v2.
i can't choose that in the menu, but it is in the system. It is no longer visible when the camera is in operation, when the fine logo is positioned above the L
And I can report strange behaviour, some settings come to mind..on the other hand I usually just dismiss it as incapabilitys of me or the models I use.
Or maybe just designchoices.
Like something with the infinity settings not holding on restart of the camera or that the camera shuts down if a script uses the reboot function. reboot is working in 1.4.1, I was mistakenly thinking about the 1.3.0 I used before.
