a peculiar padlock
Hi!
There is a peculiar padlock on my screen, I attached a screenshot of this:
This is what happened:
1/ I install a screensaver/wallpaper app called Ticke-Tack from app store, about 1 year ago
2/ Just today, I am locked on this app, but I can't seem to unlock it, tried deleting the app, but because it's open, I can't delete it. tried changing the wallpaper doesn't work, neither is changing the screensaver and I've tried everything, you named it: keychain password, screen lock, etc.
3/ My laptop seems to be working just fine, I work with it for 3 hours now, no crashes no force quit
I am baffled.
Can anyone help me?
MacBook Pro, OS X Mountain Lion (10.8.5)
