Over the last month or so I been having issues, where LastPass Sesame keeps getting sandboxed. It then takes several attempts to move the file to trusted. Is anyone else using this and having the same issues? It’s happening more and more often.
Does LastPass get updated very often? That could explain it as it will get sandboxed after an update.
How often does this happen? Does it happen after each reboot? Does it happens every two or three days?
Did you close LastPass and start it again after having moved it to Trusted Files?
If LastPass is digitally signed you can add the publisher to the Trusted Software Vendor list.
