We used to fire onchange before onblur. To reproduce: 1) Load https://bugzilla.mozilla.org/attachment.cgi?id=227653&action=view 2) Tab to the first <select> (the combobox) or focus it with mouse (but have it closed). 3) Hit the down arrow key. 4) Hit tab ACTUAL RESULTS: Output box shows blur, then change EXPECTED RESULTS: Change, then blur I have the following range for this: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=SeaMonkeyAll&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2006-03-05+17&maxdate=2006-03-07+20&cvsroot=%2Fcvsroot but that's a 2-day range; if someone has builds in between there, that would help narrow it more. Given the range, the most likely cause looks like the event dispatch changes...

I see the change between 1.9a1_2006030704 and 1.9a1_2006030713.

That gives http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=20060307+04+&maxdate=20060307+13&cvsroot=%2Fcvsroot Really does sound like bug 234455, though I have no idea how....

A testcase would be great

Oops, my mistake :) Put back the old behaviour. In 1.8 the SetFocus call is before event handling. http://lxr.mozilla.org/mozilla1.8/source/content/html/content/src/nsHTMLSelectElement.cpp#1782 http://lxr.mozilla.org/seamonkey/source/content/html/content/src/nsHTMLSelectElement.cpp#1818
