Autosuggest from TM not working?

Hello, I just upgraded to Studio 2015 and I'm trying to get the autosuggest feature to work.  As I understand it, the program should be suggesting words to me from my TM as I type, but nothing is appearing as I work on my project.  I have a Termbase activated in the project and those items are appearing as suggestions as I'm used to from Studio 2014, but nothing else.  I have all of the autosuggest options I can find activated, and there's a TM in my project..what am I missing?
