No X11 input events in DGA2 mode

You can see that this topic was already debated in the following threads :

   http://www.winehq.com/hypermail/wine-devel/2002/06/0396.html

And even earlier here :

DGA2 do not work at all for any application, it's as easy as that :-)

Well, the problem is that a fix like the one you did will be hard to have
committed to the Wine source tree as it's too much of a kludge (I already
proposed a fix like that in the thread I started on it in January of this
year).

Now one just need to find somebody committed enough to investigate the
problem and to fix it properly :-)
