Hi Alice
It's about midnight for Peter, so I'll be surprised if he
beats me to the punch here with a response.
Indeed, this is the option he is referring to. Here's the way
it works. With Internet selected, your navigation is broken apart
into smaller, more easily served chunks of information. With local
PC selected, it's kept in a larger file. The trade off is that the
larger file may take longer to initially load up.
What normally happens is that the topic displays, then
executes some script to synchronize the TOC. But the script
sometimes fails, as that particular segment of the TOC hasn't yet
loaded up. Subsequent attempts usually work. So forcing all the TOC
into a single, larger file makes the synchronization begin working.
Cheers... Rick
