I'm still at work, but i've no more time for this this weekend. Possibly on Sat I will make some more attempts. I don't use MSN nor any other instant messaging service. Next time I post, I'll just get you to try a few more things. Do try the first script exactly as I typed it. As long as the first word is Warhammer it will work without putting the rest of the title in.

If you aren't even getting a keystroke on your first Warhammer window (the one you are playing), then there is something wrong in targetting the windows. In the very least, the keystroke should go through to the active window, as denoted by the Tilde (~) in front of the hotkey. This allows that key to be passed through without altering it and without AHK influencing where it comes from (the keyboard input).

I'm trying to determine if a keypress can be sent through to a Control, which is not allowed in games like EQ2, DAoC and AoC. I suspect that it will not work in WAR.

With the second script (changing active WARs and then Sending the keystroke) I'm trying to determine if WAR will accept low level windows functions while active. It's possible WAR just doesn't accept input at all while Inactive.
