Hmmmm doesn't seem to be working when I tried to implement it. It's just creating sets as normal.

well it should, as you can see at obiwan.

be sure your maintemplateset has the lowest setid of the templatesets

I don't understand what you mean...

ORDER BY templatesetid

that's why your default templatesetid must be the lowest.

all custom header/footer templatesets must have a higher setid

Right, I installed this hack and my default style started using the global style. I don't understand? :(

Hmmm great, just realised my default style has now been deleted [of which I have no backup].

huh?

try to reverse sort order:

ORDER BY templatesetid DESC

That mean's nothing to me I'm sorry... How do I do that? And the style is gone from my database.

you have to change the ORDER part in the query into the new part
