Hello,
"button-press-event" expects callback that returns gboolean value 
(FALSE: continue signal emission, TRUE: stop it). Your callback has 
'void' return type - so you'll get random result (in most cases: TRUE).

NOTE: *all signals* with names like "*event" expects *gboolean* return 
value from callback.
