Yes, that's it! I just knew it was something I ought to know about, and 
that I was looking at the wrong place ;-) I've now changed to a 
different modifier key in the WM setup, I can see the events quite all 
right. I probably need to reconsider the way the application using 
modifiers, though (but I can blame the current setup on someone else), 
since it's probably quite common that the window manager wants to use Alt.

Alt + motion would still be passed to the app, by the  way, which was 
something that added to my confusion.

Thanks!
