Well,
For example, there is one bug in firefox: when you press right mouse click, sometimes you can do not what you want to do.
Why? Because there is another event system in Gnome (not sure about another DE).
Context menu is showing when you hold mouse button, not when you release it.
Problem? Yes. Is it possible to solve it? Yes! Just install any "gestures" plugin and that's it! (You can even disable all gestures).
Since you've install it - you will get another behaviour, like on Windows: context menu will be shown only after you release the button.
Is it workarround? Yes. Did it help? Yes.
Now I have exactly the same problem with keyboard and I'm looking for people who have found some program, allowing to fix (workarround is ok) that issue.
So, I don't think it's a magic.
(p.s. sorry for my english)
