My company is supporting a web application that needs to run on a bunch of different browsers, including old ones like IE6 at various patch-levels (dumping support for IE6 is not an option, so please don't suggest that).
We have a somewhat AJAX-heavy site, and on these older browsers users sometimes have issues. We've tried to duplicate their settings in our lab, but the amount of info you can get over the phone is limited, and so far we've been unable to duplicate many of the issues.
Has anyone heard of something like this? Any recommendations?
