Hey all, I was wondering how to handle a situation. I'm working with a programmer to create a file distribution extranet, and we're close to completion. The client experiences a bug with the application that causes the file download to fail. This bug has caused us to miss our launch date by quite a few weeks. The problem from our side of the fence is that he has one of 2 machines that can produce the error. We have tried with the same overall specs and can not produce said error. We have a spreadsheet documenting what it *does* wok on, but for the most part, we're blindly trying to squash this bug. The client is adamant that it's not his setup, and that it's a specific issue with IE and our application. Any insight on how to wrap this up as quickly as possible, with few foul words and no burning of bridges? Thanks, Chris.
