Used Windows 10 and Mail without a problem but today the Display driver fails with "Code 43" resulting in a lower resolution default driver loading. Reloading driver continually fails with same fault code. Downloading latest drivers results in message that latest drivers already installed. This problem only occurs with MS Mail, all other Office software and apps do not cause this problem. Restarting computer resets computer to "recommended" driver until Mail starts and then again this fails with Code 43.
The last Windows Update occurred on May 31st, updating all available updates as of today did not resolve the problem.
