I am not sure what is the correct way to do this. I posed a question, thought I had found the answer, posted it, and marked it as the answer to my own question. After some more testing I found that my answer does answer the question to a limited degree, but I have a new, better answer.
The symptoms point to either of these answers as possibly working, but in my specific case it was the new answer.
Am I supposed to edit my old answer? Or should I post the newer answer and mark that one as the answer? What is the etiquette here?
