sponateneous purging of a backscript?

[Brian Yennie]

FWIW, I didn't have any clever thoughts about what might be happening, 
but my one reaction was that the IDE must be making a mistake when 
trying to remove it's own backscript(s). I know that doesn't help much, 
but sometimes when two heads reach the same place it's a good sign!
