Not entirely sure what you mean..
Menues are placed under the mouse if there is space available, dialogs are placed where the OS believes they should be placed.
<quote>But in 2.0 the menu claims the entire workspace and doesn't move. </quote>
What do you mean with claims the entire workspace, because it does not for me.

What's more, when you right-click outside the menu but at the same height as some menu item, that menu item is activated.

This might be fixable. You can still left click, hit ESC key ...
