Which is reasonable, I think. Think about this a moment -- parameters 
are always evaluated before being passed. When you pass "me" in a 
parameter, the "me" will refer to the object currently executing the 
script, not the target object the script will eventually refer to later. 
This is normal behavior.

Take this example:

   addNums (1+1)

The addNums handler will receive a parameter of "2", not "1+1". Ditto 
for "me", which will be interpreted as the object *currently* running 
the script, not the future target of the handler reference.

When passing a reference parameter, use an ID or other static reference, 
not "me" which is always subject to interpretation. As you found out. ;)

If you absolutely must use "me" then you can try putting the parameter 
in quotes to force it into acting as a string. Strings won't be 
evaluated. I don't know if this will work in your situation but you can 
try it.

Now that I understand your usage better, I do not think this is a bug.
