TotalTerminal: visor no longer closes on blur

Total Terminal used to push the “visor” back up when the Terminal app was blurred, and it still uses that behavior on my work computer. On my laptop, however, this property has disappeared, and it’s driving me nuts.

I can’t find a preference for it anywhere, any idea what this could be?

You have probably unintentionally pinned your visor.

Main Menu -> Window -> Pin Visor (CMD+SHIFT+P)
