Q: Keychain access windows close

Yeah already have all my email accounts set up as IMAP. I tried quitting mail and then opening keychain access. same issues. also tried restarting and never opening mail. same issues still. For that matter i even tried isolating the computer with no internet access. same issues still show up. This seems like a regression defect in the keychain access application to be honest. it just showed up one day. like there is some sort of security setting internally that wants to close dormant windows, but is being triggered way to soon.

I also got this problem out of nothing. The list view works just fine. When I double click, I see a window with details for a specific entry, but after a few seconds, it disappears (even if I don't press the "show password" checkbox). I hope somebody can help me because I have a big problem now that I cannot access my passwords.

For the record, I run Mac OS X 10.11.4 (15E65)

I just did a restart in safe mode as suggested. I could not reproduce the problem is safe mode. After the next normal restart, I could still not reproduce the problem. So it seems the safe mode restart solved my problem.
