App glitch with Espionage

I have my Mail app protected under Espionage and earlier today I accidentally clicked on it without meaning to.
I cancelled the Espionage dialog box that asked for my password.
Later in the day I had to check my Mail and when I clicked on it, the Mail or the Espionage App would not respond.
My question is:
If I ever have to cancel Espionage that is protecting an application, how do I open it later without having to restart the computer for Espionage to recognize the application again?
Thanks!
