I called in to support and I was able to use IE as a workaround. The problem is that on the main "My Content" page when I check the box next to the item I want to share no "share" button appears at the top. Then when I enter the item details page, there is a "share" button but when I use it no sharing options are available (even public). I have updated Chrome to the latest version but still have the same result. I like Chrome as a browser so I'm curious if this is just a local machine problem. I also am posting so that others who may have my problem will have a clue if they run into this. Thanks
