HI Bridie
Are you still having the same problem? It is happening to me too. Like you, I have another (less preferred) programme I can use when at home, but unfortunately I don't have that backup option on my laptop, so when travelling I am in big trouble! I intend to take more note in future, but I THINK in the past when this has happened there has been a click in the recording at the time that the sound disappears, so I wonder if that is the problem? I used to have a similar problem with one client who recorded in DSS but his recorder would click and the file would not load beyond that point. He has purchased a new recorder, and thankfully did NOT go with Olympus this time - so I won't have the DS2 problem with him.
