Hi Kieth
I have one for you that may not have a solution.

I have a trigger set up to send a program (Songbook) to a particular monitor, when that monitor is activated. With your previous guidance, it works perfectly.

However Songbook has a feature where the user can press a 'play' button (to play a music file) and a new songbook window opens, which is basically a simplified music player. The problem is, sometimes this 'sub-window' (for want of a better term) opens on the wrong monitor.

Is there any way to set up a trigger to control a 'sub-window' created by a program?

Another example might be the 'Save As' window that MS Word or Excel creates.

Hope that makes sense.

Please disregard, i think i have fixed it using advice you've given on another thread.

To anyone else trying this, i just had to use the 'windows text' of the new window to activate the trigger.
Thanks
