Thanks for the reply, remoulder. I understand (and agree with) the need for password authentication before installing updates, I just want it to skip the automatic refresh which it does first. For instance, as I write the 'i' icon has come up saying '6 recommended updates available (2MB)'. If I click on it, after giving my p/w it will do a refresh and come up with 6 updates available totalling 2MB. Since it knows this already, I'd like it to just get on with displaying them for my approval. The refresh sometimes takes quite a long time (and sometimes not - I don't know why). It isn't vitally important, just a bit irritating, especially because, if I remember correctly, when I was using Ubuntu before moving to Mint, the updater did exactly what I want!
