Design question

Gosh, this is bizarre. All the positive comments on the new design have come from people who use Safari as their browser, but a reader just wrote to me to say that on Internet Explorer, the design is completely different and utterly illegible. Have other people experienced this? The way it ought to look is with a white background, the header white letters on a red background, the text in black letters and the links in blue letters.

Any suggestions on how I might fix this compatibility problem (other than suggesting that most browsers are probably preferable to IE)?
