<SELECT name=ao size=5 ondblclick="jsAddActivity(this);">
<option value=foo>foo</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
<option value=foo1>foo1</option>
</SELECT>

I use this code to perform an action when a browser double clicks on an option
in a form select field that is 5 options high.

Say the select form is 5 options high. Double clicking on an option triggers the
JS action correctly. Now suppose I try to scroll down through the options with
the scroll down button on the select form field. When I double click on the
scroll down button the action gets called.

This behaviour is not shown in either Opera or IE on Windows.

Reproducible: Always

hmm, but the scrollbar is part of the select element, is it not?  not sure
whether this is valid, but in any case, its the wrong component.

Mike: IMHO a scrollbar is a navigational tool and not an inherent part of a
select form field.  If action should be taken when double clicking on the form
element (in it's totality), this should be handled by some sort of div/span
implementation.  The action should be triggered by double clicking on an element
of the select list, not the navigational structure.

Precedent has already been set.  Try this: right click in the window of Firefox.
 You should get a context sensitive popup list.  Now try right clicking on the
scroll bar for the browser window.  No popup occurs.

AFAICS, this behavior is only happening in Firefox.
It's not happening in the latest Mozilla trunk build I tried.
