Thanks for your response,
I seem to loose connection at random times, sometimes after a few mins, sometimes after hours (i've read about your 24Hr thing in another post), so its not related to my ISP - I believe BT are OK for P2P sharing.
I have also made sure I have the latest Java version, so its not that either!
In the last few days I have tried simply resetting my modem when it happens & not shutting down LW or any other propgrams (no reset button so just pulled out the USB cable for a few secs) & once my modem finally gets a conection back (seems to take a while), LW does eventually re-connect by itself. Very odd!!
I'm gonna keep experimenting...! Any suggestions welcome
