With the last two builds I cannot seem to get file dialog boxes to open, for example when I try to change the default location for Onedrive, when I click change, the title bar flashes of the onedrive app, but no selector comes up.

Same thing with things like uPlay an Origin (Plus numerous other apps that use the standard file dialog box)

Has anyone come across this and have a resolution?

I ran a clean install on both builds, same result.
