This update seems to "seize" the clipboard when clearing the clipboard after 90 seconds.
- Copy Item Field in 1Password (can be anything), and paste it - Successful
- Within 90 seconds Copy and paste something outside of 1Password - Successful
- After 90 seconds, copy and paste something outside of 1Password - Failure - Nothing Happens
- Copy Item Field in 1Password again and paste it outside - Successful
- Copy and Paste same thing from outside 1Password - Successful
- After 90 seconds, copy and past something outside of 1Password - Failture
So it appears that the 'Remove copied information and authentication codes after 90 seconds' is doing something odd with the clipboard.
