The right way to go is to create the zozor object in the main and then
use evas_object_move(zozor, x, y)
in the mouse_move callback. This must work without touching the focus
stuff, evas_objects don't need
to be focused to be moved.

Hope this can help...and please don't post stuff in your language, It
require me to use a french dictionary to read your mail ;)
