Not sure about that last one, the originator seems to think he's mistaken by the end of the topic.
One less then

Nor do I, haven't seen it for a while myself.. given Xan's post, perhaps I'm merely typing slower these days.

The PM one was a variant
During CFP betas I had to rearrange (merge/split) posts a lot or ask for missing infos. Usually I sent a PM to the topic creator to let him know the URL of the merged topic or I sent a PM to members who didn't add all needed infos.
It was not uncommon to send 2-4 PMs at time. And I was plagued by that bug to such extent that I desisted.
When I got that 1 second error I was unsble to send PMs for few minutes and the time counter always specified 1 second.
It was nerve breaking to reload the PM page countles of times.
