The Rift ID thing didn't work for me when I was having this problem. The
only fix I found that worked for me was here:

I am hitting this also -- thanks for the post and for the workaround,
will try now. Can confirm this is a total productivity killer. Can you
explain a bit more the steps to employ your workaround?
