Adobe Reader 10 (or X as they prefer to call it) is a total waste of time and space. It is NOT an improvement on version 9 – in fact it is a totally retrograde step – take my advice – don’t install it. It is counter-intuitive, has almost no help system to try to find out how you now do things that were easy before (like search a document: how would everyone know that you have to right click your mouse now instead of having a search bar on top!).
Adobe will not divulge an email address to complain to under any circumstances – you can phone them but forums show that you can wait hours for a reply (if you are lucky enough to get them to answer) that gets you nowhere. Shoddy, shoddy, shoddy. Perhaps this is a company that has got too big for its boots.
