button press event

["hamb ka" <hamb_ msn com>]

Hi, all

I have a problem of getting a button press event while left clicking the 
mouse. Right click gives me both the press and release event, but left click 
only presents the button release event...
I am using a scrolled window with a clist by the way, the part of adding the 
signal is as follows:
gtk_signal_connect (GTK_OBJECT(self), "button_release_event",
    GTK_SIGNAL_FUNC(my_button_release), NULL);
gtk_signal_connect (GTK_OBJECT(self), "button_press_event",
    GTK_SIGNAL_FUNC(my_button_press), NULL);

The funny thing is that in the same application I have another code, which 
is scrolledwindow+viewport, and I defined exactly the same two events as I 
did to the scrolledwindow+clist. This one works perfectly. Both right click 
and left click raise the button_press_event and button_release_event....

What could be the possible factor that make the button_release_event fail 
with the left click in the first case?
Thanks...

Best Regards,
hamb
