First thing I would try is upgrading to the latest 6.4 release, this would bring you to 6.4.8a. This is currently available through our "main" download page located here, http://www.sawmill.net/us_downloads.html put in your email address, and then once you submit the next page has a pull down menu which shows the 6.4.8a release as downloadable, select this, then select the platform on the next page.Below is a cut/paste of "POWER USER TECHNIQUES" from the Sawmill 6.4 documentation page....
You may prefer to build and update your configuration databases from the command line, avoiding the overhead of the web interface. To rebuild a configuration database from the command line, do this:
(Command format for linux/mac/unix)
sawmill -rfcf config-name -cm cd
(replacing config-name with the name of your configuration), or update it using
sawmill -rfcf config-name -cm ud
note, if you are using Windows, you will need to open a command prompt window, then move to the Sawmill install directory and from there run the command as follows:
Sawmill6CL -rfcf config-name -cm ud
