bugs in union and intersect?

[Dick Kriesel]

They both fail with caseSensitive true.

on mouseUp
   local a,b,c,d
   set the caseSensitive to "true"
   put 1 into a["a"]
   put 2 into b["b"]
   put 3 into b["B"]
   union a with b
   -- missing a["b"]
   
   put 1 into c["c"]
   put 2 into c["C"]
   put 3 into d["c"]
   intersect c with d
   -- should not have c["C"]	
end mouseUp


Confirmation?
