How to set a background (black)
and the tekst (that I see, also from others) into another color (green or something)

Thanks for replies

Alt+K

Yeah, that is the tekst color, thnx for that, but how can i set a background color??

Alt+K...left click in the box where you want to change the background, then click on the colour you want to change it to. Change all the other colours accordingly in the same way. You can always reset to mIRC's default colours if you don't like it.

aaah,

you can also select the whole box
Thnx

You're welcome
