Small typo in Eric's code; "tiddlerDisplay" is an ID, not a class, so it
should be this:
#tiddlerDisplay {
height: 30em;
overflow: auto;
}
HTH.

The IDs are "mainMenu" and "sidebar", respectively (for the CSS
selector, simply add a "#" as we did before).
Be careful with those scrollbars though; I used to do something similar
in the beginning, but then realized it does way more harm then good.
