I am having the same problem with
www.delta.com.
I have used it many times before but lately it brings back
a blank screen and says 'done'.
See if the problem is the JavaScript.
E.g. set your Security options to Prompt
and then see if you get prompts.
FWIW I get two prompts before I see anything from that page.
So if you are seeing nothing it might be an indication that your
JavaScript support is broken. In any case replying No to all prompts
might be a useful circumvention for you.
If you don't get any prompts check to see what is in View Source.
If the source is empty too it is perhaps an indication of a problem
with DNS or your cache. Try pressing Ctrl-F5 to eliminate the latter
possibility. To test if DNS is the problem open a command window
and enter these commands:
nslookup
www.delta.com
ping
www.delta.com -n 1
telnet
www.delta.com 80
GET /
(That last line is what you can type when telnet clears the screen.)
If the address that nslookup finds is different from the one that ping
is using that could be an indication of a problem being caused by your
HOSTS file (or on NTx your dnscache). Then, even assuming the ping
is using the correct address and it is not blocked, all it proves is that that
server name has a defined address; it doesn't show that there is actually
a server there ready to receive HTTP requests; so that's what the telnet
request does; it proves that an HTTP request can be responded to
by that site.
