I've been getting, with greater frequency, a window related to OS X asking me to enter my login password. It is very annoying, popping up with regularity in the middle of different applications and streaming TV, etc. How can I get this to stop? The next time it comes up, I will take a screenshot of it and post it in case it is not clear what I am referring to.
I clicked "This helped me" as I want to watch for a few days to see if it takes care of the problem. I suspect, based on what you gave the steps for, that it did as keychain is now not supposed to lock up every five minutes. Resubmit your post for me and in a few days, I will click you as "Problem Solved" if it does not pop up anymore. Thanks so much!
