This is not correct. I do my development on FF (currently at 3.6.3) and
manage local files fine if referenced
from the initial opener. Ajax implementations vary however. ext.ajax
needs the ext.basex adapter and this fails with the latest Chrome beta
but jQuery works fine with all.
I have looked at the labs.metacarta.com implementation. Its use in
cross-platform, zero-install environment, is not quite as simple as what
we are doing - but do need the openlayers change for IE. perhaps you
could unpack for me the intent behind
this._object = oXMLHttpRequest ? new oXMLHttpRequest :
new window.ActiveXObject('Microsoft.XMLHTTP');
I am struggling to understand the intent new oXMLHttpRequest. The jQuery
management of the XMLHttpRequest object is rather more complex but it does work.
