It looks the problem is only reproducable when the focus policy
(System/Preferences/Windows) is not set to "Select windows when the mouse moves
over them". This is what I use on all my machines and that's why I wasn't able
to reproduce the problem.
It looks like a gtk/metacity problem to me, but I'll look more deeply into it
now that I can reproduce it.
