new mail window too wide

Odd thing today. In Mail, if I click on the icon for a new mail window to come up (or use command-N) the window that opens is too wide, twice what it used to be. I cannot make it less wide though if I go to the right border, the cursor changes to an arrow pointing right and I can drag the window even more wide.

If, in the In Box, if I open a message by double-clicking it, it retains the former width, that is not this wide.

I have no idea why this has happened. I have not changed any Mail settings or added accounts or anything like that.

Ideas?

So, I know it's been a million years since you first posted this, but I think I know what the problem is. Had the same thing myself for a client of mine and used all the solutions here with no success.

I found this quite by accident.

It's your signature.

There's some weird bug in Apple Mail that makes it so your signature is extending well beyond the end of the Mail window.

Open up Mail's preferences. Delete all your existing signatures. Quit and reopen Mail. That should do it. You can add your signatures back in.

I think that somehow some update corrupted the signature file. Wasn't possible to edit the existing file, but deleting and recreating worked fine.

I'll be curious to know if this works.
