I had this same problem with IE. The problem actually lies in the line it displays above. (ie. Review Date: May 4, 2005 Recommend? Yes | Price Paid?: $35.00 | Rating: 8)
If that line is greater than the width of the table it is in, then it does a hard return and puts it on the next line. Unfortunately, when it does this the Pro's and Con's disappear in IE.
As a quick fix, I shortened all the variables on the line above the pro's and con's (shorter date, using N/A instead of Not Applicable, shortened "Would you recommend" to "recommend", etc.), and it seems to have resolved the issue for now. I also reported it as a bug some time ago, but I am not sure if it ever got fixed.
