Problem deleting element of array

[Phil Davis]

If an array element contains NULL characters (hex 00) that could cause 
array problems. At least I've seen issues with that in the past - don't 
know about 6.x.

It does occur at the exact same point in the loop but there isn't anything unusual about the array that is being manipulated that I can see. The engine is just wiping it out when it's supposed to just delete one element.  I've never seen anything like it with Livecode in the 15 or so years I've been using it.
