Looks ok for me under Win98SE/IE5.5, but long ago I grabbed the free fonts from Microsoft at http://www.microsoft.com/typography/free.htm and other locations, so that may be why. BTW, my default font is sans-serif, so the Greek letters look pretty plain (pi looks like a 3-sided box); the prod (∏) and sum (∑) glyphs retain the serifs and are larger too. See Hornlo/Test for some side-by-side, so to speak, comparisions of similar entity markups. They all, except the last 4 on the page, display correctly for me. --loh.
It works fine for me under WinME/IE 5.5.
I haven't downloaded any extra fonts. --KQ

√x will work on many browsers. It's outside the standard set, but the alternatives sqrt(x) or x1/2 are both pretty awkward, so if you really need it, use it. It should be up to the author's judgment whether the use of a nonstandard character is important enough for readability to sacrifice compatibility with text-only browsers and old software. --LDC
Currently the only way to do that is by using a fixed-width font. Start each line with a blank space and you'll get that. But what's wrong with using a table? It is, in fact, a table, right? --LDC
