I use screen shots all the time (Cmd+Shift+4 ftw). But suddenly, I'll go to take a screen shot and the shortcut doesn't work. I go into System Preferences > Keyboard and see that ALL the screen shot shortcuts are unchecked. I check the shortcuts on, but then a few seconds later, they will be unchecked. I click Restore Defaults to turn them on, but they still disable a few seconds later.

Has anyone else had this? What could be causing it?

Even if I want to take a screen shot during this, I don't have enough time after checking the box to press the shortcut before it turns back off.

Thank you in advance to anyone who offers assistance.
