[xmonad] Question re Layout.MagicFocus

[David Cabana]

I've recently started using Layout.MagicFocus.  It's brilliant, I love
it.  But there is just one thing...

I still use a mouse, and should the mouse pointer happen to drift out
of the master window, all hell breaks loose as the focus repeatedly
changes in a wicked loop. Switching layouts will break out of the
loop, but it is annoying to have to do so.  I have tried setting
focusFollowsMouse to False, with no effect.  Has anyone encountered
this problem, or have a solution?

Thank you,
