how do you choose full view in category mode, full view in list mode,
partial view in category mode, partial view in list mode, not
installed in category mode, not installed in list mode ?

So you are saying that the single button has a second order effect.
Normally, you would put this 'second order effect' on a different gui
component so it could be controlled separately. In effect, the view
button tries to do two things - one is how you see what is currently
selected (list or category), the other is to select what you see. Why
on earth you would want to choose these functions with the same button
I don't know.

Yes, I know you can explain the terms to me, good design however is
self explanatory.

Where else? - I don't see it everywhere in all the gui's I use - I do
however see radio buttons and drop down lists everywhere.

No, I'm looking for a logical way of selecting the view mode.

Well, actually the column that does this is called Current, which was
pointed out to me by Dave Korn.

Choosing the fastest server could save a lot longer than 45 seconds in
download time. This functionality would be useful and could be an
option available to users if they wanted to automatically find the
fastest server.

That's a great way of investigating and fixing bugs - just say they
don't exist and it's the users fault. Wow, I wish I could fix my bugs
so easily.

Clever you. What's that got to do with anything? You see, to end up
with good quality software, you have to search out flaws, and fix
them. Just because you could install 5 years ago, doesn't mean the
installer is the best it could be.
