Easy solution. Don't use a strap. Or at least, a different strap. Problem solved..
That strap is too short to wear it diagonally like part of a Sam Browne belt, a Canon P would not fare any better in that situation.
That's the thing: I've tried multiple straps on this damn Canon 7, and nothing solves the balance issue (as Dave rightly pointed out). And this is the strap I usually use on a screwmount Leica... where it works perfectly to keep the camera tucked close to my body without much movement when walking. The Canon 7 is just a bulky unbalanced mess in comparison.
