[Dx4win] DX4WIN Demo Bug

[Mel]

The only time I have encountered "Thread errors" are with COM port 
misconfiguration... however you encountered an error when attempting to 
write the file so it might be an IO error. You don't mention which OS 
you were using. Without more information it is hard to guess at the 
problem... but I certainly would scan the disk for errors before 
suspecting mores esoteric causes. If you are using an external drive or 
a networked drive there are other possibilities.

regarding the "Demo bug"... this has existed in earlier versions... it's 
not likely to get fixed in ver 7 because Paul has been unable to 
duplicate and track it down. We can only hope it disappears or is 
mitigated in ver 8. Regarding the cause... I don't know... but since the 
"Demo bug" is very rare, it might be triggered by other errors... so fix 
the I/O problem first.

In order to ease identification of the cause, here is the messsage I sent to Paul by mail today. I did not attempt to use any Filters, it just happened when I wanted to save and exit from DX4WIN:
