When Paul told you it was "impossible" he was probably referring to the logic of the program with which he is very familiar. However there are "bugs" in code that can make it do something totally unexpected. Examples are buffer overruns, dangling pointers etc. Depending on the development language used some can be ferociously hard to track down.
I do agree with you that Paul should do something to mitigate this bug... and I think the best way is to write a transaction journal file... writing the whole log requires too much IO bandwidth... but just writing an ADIF journal file, especially if it could be written to removable media, would mean that any kind of failure, hardware or software, including the occasional and inevitable bug, would not result in the loss of data and would be very easy to recover from as you could just import the missing transactions. I really really think you should do this Paul. Please.... Mel, VE2DC Jack Shirley wrote: > Yes > This same thing happened to me. Almost exactly as you describe.
