50d back button focus

[clintham]

i would like to configure my 50d (gripped) to focus using the af-on button AND the * button.
i have enabled the af-on via custom function and am very happy with it. but the grip has no af-on button. so i wanted to use the * button on the grip. as soon as i set the * button to focus it disables the af-on button.

anyway around this other than using the * button for both portrait and landscape shots?
dont know if it makes any difference but im using the latest firmware.

I have switched the AF on & * buttons via a custom function so that the * button on the body and grip give AF on.
