Thanks for your help.
Here's the code extremely minimized.
Actually it's just a dragable box but the pb remains the same.
You'll notice that when the right button is pressed while draging
nothing happens, you just can keep drag the box. But when it's
released draging stops.
Anyway, I'd like to know how to completely skip the right mouse button events
in order it doesn't disturb the stream of the other events.

int handle(int e);
int xOffPos, yOffPos, dx, dy; //offsets
public:
Toolbar(int x, int y, int w, int h, const char *l = 0):Fl_Group(x, y, w, h,
l)

color((Fl_Color) FL_GRAY);
box(FL_UP_BOX);
}
};

{
static int xoff = 0, yoff = 0;
switch(e)

case FL_PUSH:
if(Fl::event_button() == FL_LEFT_MOUSE) //set the offsets

xoff = x() - Fl::event_x_root();
yoff = y() - Fl::event_y_root();
