Latest 1Password update(6.0.2) broke 1Password Mini (4.5.3) using El Capitan - it now takes literally FOREVER to open.
Okay, a bit of an exaggeration, but literally 10 seconds to open after the unlock animation. Plus, it's a bit flaky after that for a few seconds, not accepting clicks, and displaying lists funky. It settles down after another 5 seconds.
