problem with button_press_events

[Adrian Feiguin <adrian ifir ifir edu ar>]

I'm developing gtksheet and Steven Rostedt found a little but ougly bug.
When you click your mouse rapidly you get multiple calls to
button_press_event but none to button_release_event. I think that the
widget is recieving a double click event, but I'd like to avoid this
because it causes serious problems.
The event_mask is defined as follows:

  attributes.event_mask |= (GDK_EXPOSURE_MASK |
                            GDK_BUTTON_PRESS_MASK |
                            GDK_BUTTON_RELEASE_MASK |
                            GDK_KEY_PRESS_MASK |
                            GDK_POINTER_MOTION_MASK |
                            GDK_POINTER_MOTION_HINT_MASK); 

Any hint?

Thank you,
