I usually wait a little bit on things if they are non-repeatable and happen once, but now I've seen some of these twice.
The first is I get logged out, but it is random, happening less than once a week on average. But random, I've had it happen twice in a day now.
The other is some error that gets generated when you go to post a message that messes up the layout of the screen. I took a screen shot here:
http://www.physicsnstuff.com/wcy/draconomicon.jpgJust below the edge of the picture is the warning:
Warning: ob_start() expects exactly 3 parameters, 0 given in /var/www/draconomicon/html/includes/blocks/php.php on line 50
This second one is also random, with this being only the second time it has happened. The first was some time ago, after the site update, but too long to remember exactly when. It goes away if I go out and come back.
(oh, I also got the spellchecker window to crash, but I'll credit IE for that once instance)
