No One's Fault Except LJ...
Okay, my settings problem is not based on someone breaking into my journal, thankfully. I changed the Default setting back to where I want it, and it's not saving the damn changes.
I wonder if anyone else is having this problem with their journals.
Sorry to be complaining about this, but it's getting a bit ridiculous. Time for a short break from history junk, then go back to the paper.
