I usually take upgrades on trust, and just install them without too much thought. This time, however, I came unstuck. The theme has been change, and I cant change it back!
On reflection, I do have some general points about upgrades:-
Upgrades should be reversible - ie. if you don't like the new one, you can opt to go back to the last issue. (Very important!!!)
Developers should work more closely together with users, with a much greater flow of information. The requirement is to avoid unpleasant surprises when we upgrade.
Lando242 - I don't agree with your statements at all. I have just joined up, and this is my first post here. I got here by following the system Opera has provided. If it is wrong, and I am in the wrong place, then Opera should clean up its own mwess. It will probably do that after it has read though the comments here!
