A trivial complaint about the title field in Movable Type's posting interface…

Okay so here’s a completely trivial little irritation of mine. Can someone please explain to me why it is even possible in Movable Type to put more characters in your title field than the system can record in the database. I just don’t understand it. Surely adding a character limit would be the simplest thing to do, and the consequence would mean that if my title was too long, I wouldn’t have to wait to press “Save” to realise it. This was never really a concern until I started using the Title field to put in all the text for my linklog. Now it drives me insane.
