Well, I am using Safari all the time with LON-CAPA (it's my main  
browser), and I am using LON-CAPA, let's say, a lot ...

Also, in our student labs we are running Safari. So far, I have not  
seen this.

If the page comes back *really* quickly, it's likely from cache,  
which would also explain seeing an old result.

Now, that cache could be in the browser (I am not sure if one can  
sort of hyperconfigure Safari to do more caching than in the default  
mode, which I am using).

It could also be in the network, where some network administrator or  
service provider set up a web cache to minimize outside traffic. I  
have seen some very weird configuration in high schools. Is this on a  
standard Ohio-U connection?
