Because there have been occasions when I have changed the pac file on the
server, and the 20,000 odd students that we have here have found that the
pac file they had on their PCs had not been updated. They all then
complained that things didn't work, which should have done had the pac
file loaded. We have tested that restarting the browser did not fix the
problem; neither did rebooting the PC. The only way to absolutely ensure
it was loaded was to delete all the offline content. I don't think the
automatic setting is working terribly well, and the help information
associated with that option suggests that it actually doesn't check every
time the browser restarts. It suggests that after a while, if it finds the
file not changing from day to day, it stops checking. I don't know if
that is what it is doing, but from the help it sounds like it, and from
experience, I would guess that it is.

Cheers.
