Well doing this:

Point toDisplay = s.toDisplay( event.x, event.y );
event.x = toDisplay.x;
event.y = toDisplay.y;
event.widget = t;
event.item = t.getItem(t.toControl(s.toDisplay(new 
Point(event.x,event.y))));
display.post(event);
s.close();

makes a difference it completely freezes OS-X :-)

The thing that strikes me is that the original code works on Gtk and 
Win32 but not on OS-X which is a IMHO a:
- bug on win32 and GTK
- bug on OS-X

Until now none of the SWT guys had an answer for me which makes me 
nervous. I'm fine if somebody tells me that I'm heading completely in 
the wrong direction and the orginal code only works by chance but I'm 
really out of ideas :-(
