I used the log option, and found that it was reporting a 'socket read timeout'. I tried setting the timeout to 120 seconds, but still had the same problem.
The main cause for my confusion is that transfers work fine when I run Eudora, but not Pegasus. If it were a fault within the dll, neither would work. A packet problem would also result in error messages in both - would it not...?
From the log file...
