And my point is that you can never get software to follow the intentions of the
user correctly; and if you can't do it correctly then your users will not like
the way the system behaves.
Remember the excellent point Mathias said in relation to kwin 'I intent to
implement focus follows mind soon'
The mouse positon is not where the focus of the user is. You point this out
yourself in the fact that the toolbars forward the events to the scrolling
of the document.
Hmm; I find it puzzeling that you propose that the all toolbars should work
internally consistent. But not all of the content area should act

So, take the www.cnn.com site. It has a combobox on language selection. Do you
think the scrolling via the mousewheel can be done in such a way that the user
gets what he expects?
Hint; waiting to think is not an option; the site allready refreshed to the
language of 'your choice'..

Again; the changes that a mistake is made is high, the mistake will in lots
of cases lead to a big confusion since lots of website go to a different page
I don't think this is appriciated.
I remember you once said that the choice should be made on merit. Does the
addition of this feature (mousewheel in a webpage) give enough merit to allow
potential confusion and the inevitable inconsistencies to exits?
I tend to say 'no'. And I read enough Slashdot comments to know lots of people
agree with me.
