Canon 400d Back button focusing issue

Hi all. i recently discovered the joys of using the back button to focus instead of the shutter button but i have a small issue.

The issue is the little directional buttons at the right side of the screen now acts as a control button to manually select a AF point? i can no longer for example set my ISO(U press the Up key to do so usualy) or the WB etc and i have to turn the camera on and off to be able to use those again.

As soon as i press the back button to focus, i can no longer select ISO etc

What am i doing wrong?

It's two separate settings, using the arrow keys for AF point selection and converting the * key to focusing instead of AE lock.

Besides, you don't have to turn the camera off to use the arrow keys to change ISO and such, even if you have the shortcut to select the AF point via these keys active. Just wait until the six second meter active timer times out. Then they'll not select the AF point until you press the back button to focus next time.

cool ok nice one
