Window focus wish and mouse binding bug

[Daniel Pfeiffer]

In GNU Emacs 21.1.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-02-21 on pfdabpc

I have a window manager policy of sloppy focus (focus-follows-mouse -> t).  
Hence I find it quite irritating that when I move the mouse to another emacs 
window, the buffer current'ness doesn't follow.

I have mouse-wheel-follow-mouse -> t which is very intuitive.  But it only 
covers this one little aspect.  It would be nice to generalize this option as 
activate-window-under-mouse.

Now for the related real bug:  When clicking on an inactive buffer, the mouse 
binding of the active buffer is used.  For example in an inactive comint 
buffer, when hovering over a previous command, it highlights and the tooltip 
comes.  But when clicking mouse-2, it does a yank, rather than copying the 
input to the last prompt, as the tooltip promised.

best regards
