I run in fullscreen windowed mode, and it seems like copying the CoH (Alt+Print Screen) screen to the clipboard copies whatever was on the screen when I last tabbed in or selected the CoH screen. So I was having luck selecting a program on my other monitor, clicking back on CoH when the animation on the character select screen was at a point I wanted to capture, using Alt+Print Screen, then pasting into IrfanView. I managed to get a set of reference pictures from the power customization screen that way.
