What I do is have an invisible frame that checks the timestamp of the last
update to the chat against your last refresh timstamp.
If it's superior, I refresh the chat list.
I actually make this check without a call to the database, if you have 100+
chatters, check calls to the db can become heavy.
I just have a file that holds the last update tstamp and read this file.
The check page refreshes itself every 20 seconds (plenty enough for a chat I
realized) and has the last given value of a refresh.
You can see my chat at http://zc8.com, you have to login though.

Hi everyone,
I have designed a chat program which used a refresh function to update
the chat list every 10 second. But How can I perdict the flicker screen, or
Can anyone tell me how to re-write the program so everytime people send
message to the chat box, the chat box will not flicker at all. Oh, Please
I'm not really good at PHP, so,please give me more details on it. Thanks.
so much.

Main window --index.html (break down into two frame.
topframe for chat box, bottonframe for input message)
Bottonframe PHP will save the message to file.
Topframe PHP will refresh every ten second and retrieve the
data from the file.
