This problem occurs throughout various Sitecore 7.1 installations that we have, including clean installations with an existing database. It occurs in Chrome, Firefox and IE10, so far as we have tested. We have installations on Windows 7 local machines as well as Windows Server 2012 servers.
When editing an existing image in the media library, we can choose Attach and the "Attach a File" dialog comes up. Now, when pressing the "Browse" button to find a file, nothing occurs. Nothing is logged in the sitecore logs and no js errors show up in the console. Nothing happens.
Anyone have any ideas?
Thanks!
I also have the same problem I wrote to Sitecore support,and they registered it like a known bug on Sitecore 7.1 Initial Release . They suggest me to implement the workaround described here:
