OK, I have 512 MB of total memory with 106.66 available. Total virtual mem is 2.00 GB with 1.96 available. Again, Limewire doesn't work with my firewalls shut off (briefly) but even with them off, I still a firewall icon on Limewire. To my knowledge no additional firewall has been added. Could one have been installed in a regular update? Where can I look to kind if there is another firewall? Also, my music files are now popping and breaking up when I play them and it wasn't doing this before. The rest of the computer works fine.
