fine but loading it, then changing options turn it into a 45 minute job?

Because constructing the list of packets takes an amount of time proportional to the number of packets in the file, while modifying it for every packet takes an amount of time proportional to the *square* of the number of packets in the file, as to change the Nth row requires the widget that implements the list to find the Nth row, which takes time proportional to N.
