Description Sam Bauers 2007-05-24 08:29:36 PDT

When a javascript function is called via an onchange event on a select form element, if the function attempts to set the focus to any other DOM element then the function is run again.

This is best explained in practice by the reduction that follows.

This has been occurring only in the most recent nightly builds (currently running revision 21682)
