OK, so I'm a bad typist, and I usually make several edits after I post a new thread. (I'm a sloppy proofreader, too, and never catch all my mistakes right away.) But in the last few days, my changes won't "stick".
This thread is an example - I've fixed it several times to add a space after the close-paren (so it doesn't wrap to the next line), but when I hit edit again, the broken version comes back. Likewise, I added a P.S. in my third edit, but that has disappeared.
This is a really annoying problem, especially because of the very short "time-out" for edits.
