Rob, I'm confused. Are you seeing the 1.10.3 download offered in software update on an OS older than 10.6.8 (the last update of Snow Leopard)?

OmniFocus 1.10.2 is the last release for 10.4, 10.5, and 10.6.0 -> 10.6.7.
OmniFocus 1.10.3 should work great on 10.6.8, 10.7 and 10.8.

I do not expect we will make OmniFocus require 10.8 before many more of our customers update to it.
