OSX 10.8.5
I am using lastPass and have the appleID in there so I can copy and paste whenever needed.
Sometimes when I am told I have an upgrade I am asked to sign in to the app store. Annoying but ok. So I have generated a quite safe password - why am I not able to paste that into the password field? Any setting I can change? (I obscured the appleID in the picture below)
