Triggers loaded into editor as read only?

Ive spent a couple of hours stuffing around trying to edit triggers in the editor screen. These have been loaded from the DB as well as saving to a file and reloading.

I was able to trick toad by putting a character before the create statement i could then edit it and execute but as soon as it executes it becomes read only again.

I have a bunch of trigger work to do this is going to drive me insane.

Please help.

I was using I upgraded to still no luck.
