Since I almost never look at my site using any flavor of Internet Explorer, I was clueless to the fact that this rantfest was not working in that browser.
The problem turned out to be a little piece of code that links back to Site Meter, a free service that’s supposed to keep track whose visiting the pages.
I have no idea what changed to break things but removing the lines from the WP template seems to have fixed the problem.
It really doesn’t matter anyway since Site Meter wasn’t all that accurate and I haven’t checked their stats in months. Another little piece that I can do without.
Ah, the oddities of running your own site with only half a clue.
