Sorry to bring up this old thread. I can't edit my signature. I use Chrome and pull up the "edit signature" page. My current signature appears and the box underneath it where I can normally edit my signature is blank. The text appears there for a brief second and then disappears. I have clicked in the window and hit Ctrl+A to select all text and there's nothing there. I have also clicked "Preview Signature" and my signature then appears blank.

What happened to this feature? Or is it just broken in Chrome?

Edit: this is not just a problem for me in Chrome. I tried IE as well and the same exact behavior happens.

Thanks,
