I have the same problem. LimeWire will not save the Keep Approximately XX Connections Up on the Connections tab. I am using Cable Modem and maximum allowed connections is 6 for me. The default is 3. But when I close LimeWire and start it up again it always goes to 3 connections even if 6 is entered. I always have to reenter the 6. This seems like a bug that can be easily fixed. Let's hope!
