JB,
Yes, that link gives instructions that would have resulted in:
[misc]
project-priority=RC5,OGR,DES=0,CSC=0
[buffers]
frequent-threshold-checks=4
being added to your DNETC.INI file.
This is equivalent to what I had posted. i.e it should have worked!
The only thing I can think of is that your DNETC.INI file did not get updated. Did you choose the "0" option all the way back until you exited?
