vertical scroll bar covers text

[Bob Richardson]

I'm having a problem, only with IE, where the right hand scroll bar is
covering some of the text. Is there a work around for this problem?

Here's the page: www.writeonwhidbey.org

All the text, etc. is within the "contentCell" of the page.
<td id="contentCell">

and my CSS shows

table#contentCell { /* link table in header table cell */
width: 100%;
margin: 0 5em 0 0; /* this doesn't work */
}

The margin statement is ignored. How can I get a larger right hand margin in
this cell.

TIA
