I have a fellow who is trying to view a document from a web page https://www.smartrecruiters.com and it's allowing it.
He is able to access the Contact, and see the attachment. When he clicks on it, it pops up the download bar and when you click on Open, nothing happens.
Yesterday he was able to do so, GPO should not have changed anything, and as near as I can tell - no new MS updates were applied.
The user prefers to use IE, and honestly seems that it's the same issue in Chrome too. He states it was working fine yesterday just not today. He's complaining he can't work due to this limitation.
