This fix has now been retrofitted into the 3.1a update stream, having 
been graciously patched into update 4353 by Dan.

Anyone who had already updated through 4354 need not worry about 
missing the patched-in fix because it will come along again in update 
4417, for completeness.

Sorry for this glitch!
