<div>I can't say for sure what the problem is without looking at the log file for your example, but this is an example that works (see below).</div>
<div>The 10 x 10pt rule shows that it works. The boxes containing the `a' and the `A' are taller than the letters themselves. I'd have to check to be sure</div>
<div>there's no other space in your example.</div>
<div> </div>
<div>If you want a letter to be right at the edge of the paper, you can use MetaPost to achieve this effect. If I have a moment, I can make an example.</div>
<div>At the exact edge wouldn't be useful for printing, but it would work in a dvi, ps or pdf viewer.</div>
