I am running Limewire 4.0.8 PRO on Win XP SP2, and I have a 512/128k ADSL connection and I am behind a router with the required ports forwarded. I also have Force IP on. Now my problem is that sometimes when I start Limewire and go to the connection tab, I appear as a Leaf node, and other times I appear as an Ultrapeer. Why am I not an Ultrapeer 100% of the time? No network or software configuration changes have been made between each run of the program.

Any help would be greatly appreciated.
