Just for the record, I think I've resolved this.
The problem seems to be my <HEAD> output function. It contains 2
placeholder statements for links to an external js and css file. If I
didn't pass a value, it would print out something like this:
<link href="" type="text/css" rel="stylesheet" />
These blank href values in these statements were causing my script to
reload (in Firefox, at least).
Anyway, now I know. Hopefully, this will save some trouble someday for
anyone else having this problem.
