Thanks for the suggestion.
I'm remotely accessing an Applie iMac running Mac OS Sierra with Safari 10.1.1 from a Windows 10 Pro box running C# .NET code with WebDriver 3.3.0 via java running Selenium Standalone Server 3.3.0 (hence the java in the exception below).
I'm executing
driver.Manage().Window.Size = new Size(800, 600);The window size remains the same size and it bombs out with this exception. We just don't seem to be able to interact with the Safari window itself.
