I too bought Bella Coola some time back and went to check to find mind is also still at 1.0.
Can I ask where the Reviewer got his review copies from that were both at Version 1.5 ?
If 1.5 is available then am also wondering why my download in the store has not been upgraded yet as per the other OP ? I note the Store advertising says "XP12 when available so I assume someone has responsibility for it.
Would be nice to have an update from the Reviewer on this as no-one else seems to know anything !
