Locks App but can't cancel or go back if u click app by mistake

It locks the app however if the app is clicked by mistake, you cannot go back or cancel. One of the symbols to cancel is not even on a computer so wth. There should be a way to cancel an action. I want to go to pro but this is the reason I won't.

Does the job. Locks my Evernote file on work computer

I have a work computer that I installed Evernote on. I bought this software to lock Evernote to keep prying eyes out. It works. Easy to use as well and good service.

Does What I want, but not what it should

I wanted to disable Safari entirely. An internet search showed this to be impossible, except for force deleting system files through terminal.

Instead I decided to password protect it. I set the password, hit OK.
Trying to open the program stops the computer. The screen blurs, but no password or dialog box of any kind appears.

The only way I've found to make it go away is to hit command alt Q.

This is okay for me so far, since I dont want to ever open the program anyway.
