The window didn't snap back aggressively. It reassembled itself. First, a ghost of its border. Then, the title bar, stark and blue.

Alt + Space, then R: This is a classic "power user" move. Alt + Space opens the window menu (even if you can't see the window), and pressing R selects "Restore."

Task Manager: If the app is frozen, press Ctrl + Shift + Esc, right-click the app, and select "Bring to front." If that fails, "End Task" and restart the program.

If you have multiple windows of the same app open, hovering over the icon will show thumbnail previews. Click the specific preview you want to open.
