nope I dont mean that
I mean idle in your computer not only in mIRC. mirc idle grows, but maybe you are doing something else in the computer. well, you are there but not looking at mirc. But, when you go lunch or something, mirc idle grows, and windows idle do so, like in messenger, that sets you away by default after 5 minutes of inactivity (mouse move or key pressed wherever).
So I'd like to get windows idle
