Yes, wait_key() is not for GUI use. You need to trap the keystroke message 
from Windows. If you are using win32lib, this is done by setting a handler 
routine for the w32HKeyDown event.

eg.
 procedure onKeyDown_toolbar(integer self, integer event, sequence parms)
    integer theKey
    integer theShifts

    theKey = parms[1]
    theShifts = parms[2]

    -- React to the keystroke.
    if theKey = VK_... then
       . . .
       closeWindow(launchwindow)
    end if
 end procedure
 setHander(mytoolbar, w32HKeyDown, routine_id("onKeyDown_toolbar"))
