Ok, how would I go about refreshing what's in a output window?
Ok, how would I go about figuring out what you mean by "refreshing what's in a output window"?
Use common sense and write your posts so that someone who can't read your mind will still be able to understand what you're talking about.

Ok, example:

Say I have a Private Messaging Window, you open it and use it to communicate with another player. I would I go about clearing the messages off of that window?

Messenger(mob/M in world)
set hidden = 1
PM(M as text)
src << output("<b>[src.key]</b>:[M]","PMOut")

Why would you want to if it's for private messaging?
In response to Vic Rattlehead
I want to make it where you can clear the window if you want.
In response to Chwgt
You can clear an output control (and other controls) by outputting null to it through the output() proc.
(For future reference, 'refreshing' is not 'clearing'.)

Thank you.
