Flapjack, I posted that macro window 'how-to' here in the forums somewhere...I think *runs off to look......back* Well, it's buried somewhere, so I will just put it here for you :D
you can create one of those windows by using /custom_window "Some Title" -- you can still do it via text file editing, of course, but the command will make it easier.
It should look like this in your CoH Data folder:
The window will always default to the upper left, and you will have to move it to where you want each time you log in. I usually create a macro and then copy/paste it into my chat bar. After I hit 'enter', the macro winds up in a free spot in one of my power trays...I then grab it and move it to the window and delete it from the tray.
Hope this helped!
