No, I keep hoping that I don't have to spell out everything in 
nauseating detail. :)

Previously, if there was nothing in errorstring, it was also undefined. 
Obviously if there is a message there (as both you and I have 
demonstrated to be true in the past) it had to be defined.

The current state with the 1.06-RC is that the field is empty, but the 
variable is defined. That means that I can't just wrap my error-checking 
routine in 'is (defined ...'  I now have to do a string compare. (In 
fact it's worse than that, I have to do both.)  That's bad.

Also, you ignored the other issues that I raised in my previous message 
about errorstring. It would be great if you could respond to those as well.
