Quitting Word Takes a Long Time When Using Contract Tools on a Computer with a Touchscreen or Stylus
What happens: When you quit Word (by closing the last open document, for example) while using Contract Tools on a computer with a touchscreen or a stylus, Word temporarily becomes unresponsive (freezes, hangs).
What this means: Most likely, this behavior is attributable to an issue with certain versions of Visual Studio 2010 Tools for Office Runtime (see Prerequisites for Installing Contract Tools to learn about other Contract Tools prerequisites). Visit Update rollup for Visual Studio 2010 Tools for Office Runtime for a description of this issue and its resolution by Microsoft Support.
What you should do: Update Visual Studio 2010 Tools for Office Runtime to a more recent version. An installer for version 10.0.60828, released January 12, 2018, is available at https://www.microsoft.com/en-us/download/details.aspx?id=56961.
