I see what you were driving at! Once System.Time eliminates the
InitCommands section from being the culprit, then the balance of the
file can be debugged by process of elimanation - which is _exactly
what I've been doing by commenting out blocks of text. I did find the
problem, BTW! A missing closing " in one of the Network items.

I use diff all the time - good tool! Thanks!
