Using Windows ME here, and I can't hear any clicks. Sorry, but I don't know
how to 'fix'.

This one is a real pain. It appears that the List control grabs focus again
after a double click because there is a mouse up event after the double
click. With this in mind, I've recoded your example to cater for this...

integer dbc dbc = 0
procedure onMouselookup(integer self, integer event, sequence params)
if params[1] = LeftDoubleClick then
 dbc = 1
elsif params[1] = LeftUp and dbc = 1 then
 setText(focus,"by mouse")
 setFocus(focus)
 closeWindow(lookup)
 dbc = 0
end if
end procedure
setHandler(list,w32HMouse,routine_id("onMouselookup"))

However, it did find a situation which might of caused some bugs elsewhere
when a control in a closed window tries to take focus. I've now catered for
that situation, but I'm adverse to coding a special case for the List
Double-click effect.
