Thanks, there's no problem
Just a last post :
For you tomjbyrne, and those who are interested, I added these commands, which allow you to turn on or off AutoForeground (that's useful, because if you do something important, you don't want to be disturbed with Messenger windows !!)
The 2 commands :/afon (AutoForeground On)
/afoff (AutoForeground Off)
(setting will be saved into the registry)
