I've been using Gmail for a long time. When I replied to someone's post, my reply used to be added at the bottom of the so-called "conversation" just after I sent it. Recently it doesn't -- I get a message that "your mail has been sent" or something like that, but I don't see my reply at the bottom. If I exit this conversation and come back to it, I see my last reply. I find it a bit annoying. Does it happen to anyone else? Is it something with Gmail or could it be Firefox 2 that I'm using?
