Oops, right, you're using a popup. Okay. In that case, the script waits 
until the menu is gone before continuing. So you don't need to know 
whether they selected anything or not, just deselect your object after 
the popup call. Like this:

on mousedown pBtn
   if pBtn = 3 then
     set the backcolor of me to "blue" -- or any object
     popup btn 1 at the mouseloc -- handler waits here till menu is gone
     set the backcolor of me to empty
   end if
end mousedown

In the popup button script, handle the menupick normally and ignore all 
the selection stuff.
