Starting yesterday, a lot of my email messages have text that has been replaced with little A's each surrounded by a box. I just got one with a blue link, and the whole thing is 30 of these A-boxes. Yesterday I had an email that was fine, but when I hit reply, the whole message thread became these A-boxes. It just started happening, and it's really weird. I'm running the latest and greatest everything on here, and this coincides with me doing the latest OS X upgrade, except that was supposed to just be for RAW camera support.
