Hi I've been using that COPY PUBLIC LINK from dropbox.com for years and at first it used to actually copy it to the windows copy buffer as it should. Over the past couple of months it would pop the address as it should but it stopped being able to automatically copy to the copy buffer, but luckily i could still do it myself manually by manually selecting the text and hitting ctrl-c. In the latest build of dropbox.com, it doesn't even list the address to the file anymore and obviously it couldn't copy to the buffer beforehands but now i can't do it manually either! 
so i can't share any files from dropbox.com right now!
I've tried in both google chrome and firefox and same issue with both. As for which version of windows i'm running, it's the up to date win10.... Thanks in advance.
