Any message sent to popup menu (btn) when nothing is selected?

[J. Landman Gay]

The menupick message doesn't fire at all when no selection is made from 
a popup button, but you do get a mouseLeave message. It might be 
possible to track a local script variable to catch when that happens. 
This may need some tweaking:

local sMenuItem

on menuPick pItemName
   put pItemName into sMenuItem
   switch pItemName
     case "choice 1"
       put "case 1"
       break
     case "choice 2"
       put "case 2"
       break
     default
   end switch
end menuPick

on mouseLeave
   if sMenuItem = "" then
     doDefaultStuff
   end if
   put "" into sMenuItem
end mouseLeave

on doDefaultStuff
   put the seconds
end doDefaultStuff
