Thanks for sticking with me. I tried stripping it down again, but then
the stripped down version worked (even with the problem line). That
means I need to take a couple more passes at it and figure out what else
is working with this line that causes the problem.

I did determine that it is not the name of the $action variable or the
"action" POST value. If I manually set $action to "login", it causes the
problem, but if I set it to "loginx", then the post values come through
correctly.

I didn't write this script, and I'm seeing the same problem in
phpMyAdmin, so I don't think it is a coding problem unless it is an
incompatibility between php4 and php5. I still need to track it down
further. I'll let you know what I find.
