IE Rendering Issues

What I write isn't necessarily what you see.
Testing can show the presence of errors, but not their absence.
Stuart points out that some essays (like WWW2006) and some features (like the “Wheat/Gray/B&W/Green” style selections) don't work on IE.
A Google search turns up the likely culprit for the more serious problem. I'll look into fixing it when I have a chance, until then, use a better browser.
