I've now tried two XP systems (one bare metal and one VM) and a couple of
versions of ALLFIX. to sum up:

6.024 DOS - freezes the DOS window, no log entries. ASETUP works.

6.018 Universal - seems to work, but ASETUP causes NTVDM to crash. I tried
running the ASETUP from 6.024 DOS and it read the config OK, but I'm seeing
ALLFIX refuse files in echoes that I have my uplink set to receive files from,
and password errors on TIC files with the same password I have set in my
config.

5.13 DOS seems to work, but I'll need to reconfigure the whole thing, which is
ia pain.

Any suggestions?
