It seems that my answer is now a bunch of lost bytes in the cruel world of usenet. God bless the mighty sent messages saving in gnus.

Note that this is just a guess. Yep, I think the problem is here. But now the question is, is it worth doing a `frame-focus-p' compatible with X and W32 (and more ?)? As said, It'll be a great thing for modules wanting to do something iif the user is not concentrated on emacs. I'm wondering if this patch has to be more than X/W32 compatible; In fact, I don't know if mac's cocoa is managed in the same way.

By the way, the proposal of rgb provides a nicer way to use this
functionality, but I'm not sure this is really possible to have focus
hooks on a w32 system, isn't it ?
