Make the AJAX category window taller?

I’m not sure what you mean?

In wp-admin.css (wp-admin/ directory), look for:

#categorydiv div div {
height: 12em;
overflow: auto;
}

Increase the height attribute. (CSS!)

Haha, can’t believe I didn’t think to look in the CSS file! D’oh.

height: auto; did the trick. Thanks. ??
