Tool shortcuts not snapping back in OG7

in OG6, I typically keep the Selection Tool (v) selected at all times, and use shortcuts to temporarily switch to the Hand tool (temporarily holding Space) or the Zoom tool (temporarily holding Z). When I release the Space or Z keys, it snaps back to the Selection Tool automatically.

I notice that in OG7, clicking Space or Z switches the tool and it does not snap back.

How can I change this?
