from mirc help:"Event, Message, Highlight
Whenever a new message is displayed in a channel or query window, mIRC highlights the switchbar icon for that window with the chosen color."
How can i know from script when window highlights? And what color higlights in that window?

The color:
Color of the text on the switchbar is the highlight color

Deturmining if its highlighted:
I would assume the $window identifier, with a property (im guessing) like .hl or something of that nature.

The property is sbcolor (returns null, event, message or highlight).

oh.. i didn't saw that property in help.. thx u =:-)
