Hi BWhit,
Sorry for late reply, as I was on holiday for a few days.
The issue occurs for the duration of the browser, until I open AVAST passwords and enter the Master password.
At that point, when I go back to the browser, the password has been filled in.
The browser's password icon shows a red padlock.
Also, when I disable the "Lock Passwords after closing the app", along with the other 2 options, everything works okay!
Cheers Kelvin
