Actually it was reply 41 with the correct answer.
Thanks for the update! I’m so glad it worked out—I was hoping it would! When you first posted, I thought, (1) this sounds like a difficult problem to diagnose online, and (2) if there’s an answer, it’s on FR. Can you even begin to imagine the clueless, useless replies a question like this would elicit on DU? Kos would be as bad. FReepers are so amazing.
Props to you, RL, for sleuthing it out. I learned something today!
