Thanks again Stief,
In the bug report, the only thing I could find which is close to what you say is:
Acceptor: 1
in the listing thread section.

For the OSX firewall tip, the 'sharing' section which I should go into is shaded and not available to me ?!?!?

I have another query, does it make any difference if i run the same searches again when restarting LW, ie if the d/l is already in my queue and incomplete, does re-searching help? As well, does refreshing searches periodically make any difference. A few times I have done this, it does seem to 'help' connecting to d/ls

Thanks
