I have been using Blank Canvas Gmail Signatures for a year+ without a problem -- I love it.

Over the past week, however, it has stopped working in my Gmail account. I have another Gmail account, and it sometimes works in that account. It's been difficult for me to pin down any reason why it would work in one and not the other. I often have multiple tabs open, so I've tried running the account without multiple tabs, and that hasn't solved the problem. I am also running a Remember The Milk add-on -- but I've also been using that for a year+ without interference until now.

I'm using Firefox 3.5.7; Mac 10.5.7; Blank Canvas 1.11.13; Remember The Milk 1.0.4.

Help appreciated. I miss my Blank Canvas.
