Sadly IE6 doesn't so you have to use an expression for IE6, then set the max-height for all other browsers:
div{
_height: expression( this.scrollHeight > 332 ? "333px" : "auto" ); /* sets max-height for IE6 */
max-height: 333px; /* sets max-height value for all standards-compliant browsers */
overflow:scroll;
}
Overflow:auto would most likely work in most cases for have any extra spill over.
