When I tried to reproduce the same at my end the button created by me was still visible & working, could you please attach the workbook to analyse further. Also I would like to know if the buttons functioning still exists in Tableau server or is it even disappearing in Tableau server.
I am happy to attach my workbook so you can check where the issue might be.
Open the Workbook below with the desktop version, you can see that the buttons (green arrows) are working and let the user jump from the table of contents to DB's and back to the table of contents.
However, if you open the Workbook with the Reader, the button on the DB disappears.
Do you see what I mean?

I have some good news and some bad news
The good news. is that your sample works just fine for me in both Tableau Desktop 8 and Reader 8. In both cases, the green arrow shape appears, and I can access the Menu-based action from it to nav to the second dashboard.
The bad news? It still doesn't work for you
Perhaps an uninstall/reinstall of Reader is in order?
I know, this is bad news :-)
I even reinstalled the reader again and I still can't see it when opening with the Reader.
The good news: Everyone I talked to so far can see it, so the issue is minor.
Thanks for your supoort!
