Recently upgraded to Studio 2015 and have come across what seem to be several bugs.  One of them is that the F3 button isn't working for Concordance search.  If I highlight a term in the source and hit F3, nothing happens.  (In 2014, this was buggy for me too, sometimes I had to hit it twice, but it would eventually always work)  If I right-click on the highlighted word and select Concordance search in the context menu, then it works as expected.  This is kind of a bother because it slows me down.  Does anyone else also have this issue?

I feel like the source of the problem might be related to the autosuggest feature using the Concordance search functionality, but I have nothing concrete to actually base that on, except that the autosuggest stuff wasn't there in 2014.
