OK I must be missing something...
I'm working on my third site with 3.5.3 and on this site (none of the others) all the code areas in ATO are closed down to show only one line. So every time I go back to make a change I have to elongate the code window/box/area what ever you call it. Which as you know in the Add html/css inserts section thats a big space. It's a pain!
Is there a setting somewhere that keeps these open. I'm working on a localhost but my second site was as well but did not do this.
