Perry,

>Just out of curiousity, what's an example of when you would want to do something like this? Where an operation would be performed based on a select value of the combo box, before the user okayed the value. Especially on a web page. It would drive me batty if the browser updated if I clicked my mouse wrong.

How about a web page with several select dropdowns, radio buttons, checkboxes, etc, whose values or possible options change based on the first deop-down selected, but you don't want the cost of another hit to the backend?

The onchange can call script that adjusts the values of other controls, hides or shows certain items, etc.
