Hi Carlos,

IIRC every program running connected to  the X Server has a top level
window (which can be = to the Window manager container for that
program) and this address must be the same for all cases... a program
can have N windows but always exist the root one...

Here's my point, why the 3 resources returns a different window
address for the same program... at least 'xrestop' uses libXres to get
that information...

That line was very useful, thanks :) ,  but I still wonder why they
return different values :/
