Focus follows mouse & Fvwm (new user)

[Tristan McLeay <tristan@cassowary.org>]

I recently upgraded to the Debian Testing (reinstall on a new hard 
drive), and it seems that my long-time favorite window manager, 
Sawfish, is broken. So I've set out on a quest to find another window 
manager that supports focus follows mouse.

A lot of WMs claim they support it (or its cousin, sloppy focus), but 
it's far too easy to have a window under the mouse without focus. For 
instance, after a drag and drop, or if you open a menu in one window 
and close it while the focus is on another. I tried using Xfwm4, and it 
seems to get confused if you pass more than a couple of windows!

I've just started using Fvwm2. I suspect an ancient window manager is 
less likely to get "updated" in such a way that it breaks, so it might 
be the place to stay. But although it has a working "sloppy focus" 
model, if I enable:

   Style * MouseFocus

I still seem to get sloppy focus. Does anyone know why, or what I can 
do to fix it? I can work with sloppy focus, but I would much prefer it 
if when my pointer is over the desktop, no window has the focus. I 
don't really pay attention to window decorations: I just assume that 
wherever the mouse pointer is, that's where the focus is.

Also: Everytime I get an email, Fvwm switches to the desktop my email 
client is on and raises the window. Does someone know how I can disable 
this behavior?

Thanks!
