Navigator 2.0, Internet Explorer 3.0
<SELECT onChange="handler-statements" ...> a definition of the handler select.onchange a reference to the handler select.onchange(); an explicit invocation of the handler
In the Windows versions of Navigator 2.0, when the Select object is displayed in its drop-down menu form, the onchange() event handler is not invoked immediately after a choice is made; it is not invoked until the user clicks somewhere else on the page. This bug has been fixed in Navigator 3.0.
This is a severe enough bug (on a very common platform) that onchange() should be considered nonfunctional in Navigator 2.0. If you require immediate notification of changes, consider replacing your Select object with Checkbox or Radio objects, and using their onclick() event handlers.
