Forums Scripts & Popups Changing text AFTER it's displayed?

I'm already using haltdef for displaying text in a channel, but don't think that's the root of this problem. The windows the text need to be replaced in are still normal channel windows, not custom.

The problem is that it's apparantly not possible to manipulate the channel buffer at all (except for adding a line and clearing of course). However, like I said, it works perfectly on a custom window, preserving all the color, so I would guess if the command worked on a channel window, it would do so as well.

EDIT: ah now I get how you would go about changing the text, by saving the channel, manipulate the file and reload it.. But that's a really long way, involving disk operations and searching in a file, so even if it preserved color, certainly not optimal. the /rline command would be better, if it worked..
