Hi - Just got a reply from "Tuna" .......

Quote.."I take it you are subdividing one face, then selecting the other face (adjacent) and then subdividing that one.

Do this.. Subdivide the first face, then look at the second one. count the edges. It now has 7 edges because the first polygon you divided added more (to that side). This is the reason the subdividing is taking a strange pattern, because you arent applying it to a 4 sided polygon.

Now start again and select both faces at once and subdivide. They should now be neat."

And he's right - ! Cheers Tuna if you ever see this...
