I've installed 0.85, and there's no difference. To be clear, SSMS does work so far; it appears the issue is only Visual Studio 2017 (and maybe only with their most recent patches).
I think the problem is this: when I move an app over VS2017, on another group I'll see the message, "Cannot group a window that is not responding". However, when I click on VS2017, there doesn't appear to be any issue with the app.
