Is there an event for frontmost change?

[nanocyte]

Is there an event that will tell me when the VI looses frontmost? I'd like to make a sort of deadman trigger that fires when the front panel isn't frontmost. If it comes to it, I'll poll FP.isfrontmost.

Use Property node for the respective VI and you will get whether the VI FP is Front Most

Look at the Application class event called VI Activation (or VI Deactivation, if your version is new enough). You might need to activate scripting to see it.
