I prefer the in-game option, especially for multiple screen shots. (here's why)
1. In-game (Alt-S) only takes a snapshot of the monitor you're playing on. (good in case you have another monitor doing something else)
2. We can take multiple screenies in-game (Alt-S). Not so with Print-Screen. Print-Screen will overwrite the previous image if you use it more than once.
Just create a shortcut for the AHIII Screen saves. You can make a desk-top shortcut, pin it to start, or even pin it to quick access if you so desire.
It's really not so hard to just drag & drop the image into Paint, once you get things arranged how you like them.
I'll stick to Alt-S
