Chuckle, so is mine Dave.  Mouse, holding breath cuz I have a finger on a 
button, is turning blue and finally exhales in desperation sort of thing 
I guess.  Particularly against the left margin of a string. I can't see 
a single reason why a drag the mouse copy has to die if the mouse 
moves .0000001" past the left margin. But I didn't write it so I've no 
clue why it doesn't just take the whole damned highlighted string & be 
done with it.  <exasperated sigh>
