Hhmnn...we had hoped this issues were solved with 1.7, where we fixed an erroneous nslookup we were making that was at least causing some of the freezes. You are not firewalled, is that correct? I strongly suspect the issue has something to do with accepting incoming connections (keep looking at that connections tab!!). This is also strange because most users do not experience these problems (my girlfriend, for example).

Are you maintaining a high number of connections? I would put the likelihood at about 50% that the issue has something to do with the networking, particularly connections. Do you get the problem when you're not uploading or downloading files, for example? Also, you could try holding down the control key as you select the LimeWire icon. This will bring up a menu with an "Open" option. On some Mac OSes this will create an output window that will display any error messages returned.

Thanks very much for your help. Are others experiencing these problems? We definitely lose track of the forum sometimes, so I'll have a look around at other threads.
