The student comment is very helpful.

If what I think is true, this will not happen at other schools:

* We have the kids go to http://msu.lon-capa.org/
* Further form submissions go against http://sN.lite.msu.edu/

So we are switching from "zone" lon-capa.org to "msu.edu" - now if that 
is what happens, the bug is actually at Microsoft, since we already 
switched zones at login time, not at the first subsequent form 
submission. All of this would be a new "feature" of Windows XP Service 
Pack 2, which only came out a week ago or so.

I have asked another student who has this problem to come to my office 
hour on Friday afternoon with her laptop. Hopefully I can explore all 
of the details.

We need more $@%#& Windows test computers.
