Okay, last night not only did I triple check I had closed the blogger editor, I closed the window. Then today, I copied the link text (the file I edit for the linkee-poo has a lot of other stuff in it, things that accumulated during the crazy years, clips of text, etc that I really should finish closing out and putting where they need to go), opened a new blog post, and pasted the text there. Published that blog post. Opened the draft linkee-poo, copied out the rest of it, and pasted that into a new file as well. And then I deleted the old working linkee-poo post.
So what happened tonight when I got home and opened my browser and went to blogger, it took me directly to the old linkee-poo working post (even though it no longer appears on the list). But it did throw the accustomed error when I closed that window. So. it maybe a PIA, but I have the work around (as long as I remember it) for when I'm editing on multiple computers.
