I was writing reply in thread. I left computer for a short time to eat something, returned and continued to write (say 3-4 paragraphs total).
When I clicked post reply I got message that I am logged out - it is annoying, but no matter. There was login button, and I have clicked before "remember me" (although sometimes forum does not remember/recognize that I did that - say 10-20% of time), thus I was automatically logged in.
However what pissed me is that I LOST my entire post!!! It was not posted when I was logged in. It was lost from "reply window" below messages in thread (even when I did click "back" button).
Sometimes I notice that when I write reply and do not post it because of whatever reason it is remembered in thread when I come back. Now - nothing, at least 20 minutes of typing lost.
