empty selectedChunks fails to return insertion Point values

[Sannyasin Sivakatirswami]

I have a palette of html mark up tools that operate on the top window. 
I am unable to get the insertion point for an empty cursor from the 
selectedChunk function (it used to work!). A test button in the palette 
with its traversalOn set to false (so as not to deselect text in the 
top Stack).

Simply:

on mouseUp
   put the selectedChunk
end mouseUp

If text is selected in the top window we do get the expected response,
e.g. char 4633 to 4654 of field 1 so my button, the field, and the 
selectedChunk function are apparently OK.

But, if we simply insert the cursor somewhere and press the same button 
we get empty, zippo.

But, the function, as documented, should return a string like this for 
just an insertion point:

char 51 to char 50 of field 1

===docs:
Comments:
The return value reports the selected text: the startChar is the first 
character of the selection, and the endChar is the last character.

If no text is selected but the text insertion point is in a field, the 
startChar is the character after the insertion point, and the endChar 
is the character before the insertion point. In this case, the endChar 
is one less than the startChar.

Why is this not working?  OS X... Rev 2.2 Can anyone confirm this is 
failing also on their Mac?

OS X 10.3.3

This is a nuisance, (obviously) as I have to now prompt the user to 
select an empty space for insertion of stand alone elements like

<hr class="mainHeadLineRule" />
<br />

when what is wanted is to simply place the cursor then click those 
respective buttons on the palette.
