I know this isn't the version on my laptop because it's very different, but in this version (won't let me upgrade either on this for some weird reason) and every time I try to quote someone to reply, whether in PMs or in a thread, the message disappears. I mean, it's a blank screen in the reply box and when I post or send the message, it's blank.
Quick post however does work.
Very weird. I'll try to upgrade to see what that does.
And the log out is taking fewer and fewer clicks now I've noticed (in all versions of my browser.)
