We all know that posts sometimes accidentally get sent from Anonymous Monk because the user's session got logged off.

…fairly obvious. Why I replied with snark, asking for a patch, knowing that the poster would never deign attempt to write code to address this “known problem.”

All you have to do to prove this is a problem, or to allow someone to explain what you or your agent/env is doing wrong, is to capture your sessions here with a browser dev tool (even current IEs have a good one at this point) and then forward the info once it happens again. This is not rocket science brain salad surgery. This is Help Desk 101.
