I can't be sure without more details about what your setup is, but I 
don't think it's a problem with PHPlib. If I were to hazard a guess, it 
sounds like there might be some sort of transparent proxy between you 
and your clients that might be causing problems.

Again, I can't offer much more specific help than that. If you'd like to 
send some example code or something (Do you use PHPlib authentication on 
this page?), or describe in more detail how the users connect to the 
server (i.e. from a local network? from the internet? dial-up? 
broadband? Major service provider, like AOL?), then perhaps we could 
help you more. Otherwise, your best bet would probably be to either 
break up the table into multiple pages, or maybe try cacheing the 
results into a static html file every so often and having the users load 
up that instead.
