I appreciate your feedback, silversurfer. I must say, I felt a bit as though I was being scolded for my oversight.

The thing with the saved session shocked me because I had just told the commenters that I would be more careful next time and then, I accidentally did it again.

I use like 6 different imagery layers when I'm mapping in Alaska and the idea of a saved session that reloads all those layers the next day seemed like an excellent idea. But there are drawbacks, as I learned.

Thanks again.
