Easy to install and use.
Running this on Vista, it interferes with shutting down. I have to manually close it and I get an error message each time. Furthermore, when you open it the next time, it does not retain your bandwidth tally. The Totals Log utility does not retain the information between sessions. This makes it useles for monitoring months or years, since people need to turn their computers off more often than that.
