Since upgrading to SDL Trados Studio 2017 Freelance last year, when I click on the view tab, the view box that appears usually only contains a blue ribbon at the top and the rest is all grey.
Also, when I click on the view icon at the top left to view a PowerPoint document, PowerPoint opens showing an empty document.
One more thing, I find Studio 2017 unstable. It crashes several times a month. I never had that problem with the prevision versions of Studio.
