Norton IS 19.6.2.10
Win XP Pro SP3 - same problem on two machines.
Just noticed that Insight Optimizer no longer appears to do anything - it runs for one or two seconds and stops.
Tried manually launching Insight Optimizer (as an administrator) and it does the same.
If I manually run Windows Defrag on boot drive it does need to defrag and takes a long time, as expected.
Any ideas why Insight Optimizer is not performing defrag please?
Thanks
