I had not used the thumbs up function before today, but thought I would give it a try. It was going along fine until I clicked on one and it became a thumbs down. I tried ti figure ou what had gone wrong and I think I gave it a thumbs-up before it returned to a thumbs-down once again. I did not touch the thing again after that. What did I do there. Is there any way to fix what I did? I would hate to have a helpful poster be saddled with an erroneous thumbs-down.
