Screen Opens on Open

First, I'm a dumb guy, and I feel like this is something that is probably intuitive to all other users.

But for the life of me, I can't figure out why, whenever I open the display of my sleeping MacBook Pro; or various other versions of launching the finder, logging in, etc.; the "main" window (top right corner shows the preset, as well as the preferences button) opens automatically and comes to the front.

It didn't used to do this. What changed? How do I change it back?
