I brought this up in the dev app thread as well, and completely agree. There's a reason that action games don't put mouse functionality on the in-game score screen, because it is
incredibly annoying to lose control of your character when you're checking crews, checking for disconnects, ship names, etc. In that thread I proposed an alternative solution similar to how TF2 handles it, which I'll post here for the benefit of those not in testing:
"Just have big button that says "Mute Players" on the escape button screen, which displays a dialog with all the player names. That way you don't need to destroy existing functionality as it does now."
