I have exactly the same behaviour I described above... Is your OS 64 bits?


Hi.

I tried the first example pruebagtk.tar.gz and no problems. 
I tried the second example prueba.tar-gz, which uses the QT, not shown
in the debug code of the key pressed. Is that wrong? 
I use: 
Ubuntu-9.04 - 32 bits 
Gambas-2.15.2 
-Gnome

Regards.
