not sure what you mean, i will google your expressions to see what it comes up with
Works
fine with ie7 which is the oldest version supported by Microsoft themself.
Support for olderversions might only by supplyed by MS-partners.
works with ie8, firefox, chrome, opera, safari
howewer as for ie6, No go, IE6 and earlyer versions are obsolete
and will not be supported by me. and proberly many others aswell..
the thing with companys forcing ie6 is bs,, i work for Siemens, and are
using a "global" network, with forced browsers, howewer i can still use
alternate browsers, FF etc..
So sorry older browser versions is just weird, they dont support modern css, html, etc.
and other implements which is used on most websites around the web
-- PS / EDIT
its not my mod, im not using anything vbulletin 4 is not, so if you cant use it
then you will have features from vbulletin unavailible to you!!!
maybe read up over at vbulletin.com about older browsers and vb4
im only using resources supplyed by vb4.
