As you may know the Webviewer in FileMaker uses Internet Explorer version 7 for rendering websites, even if you have a newer version of Internet Explorer installed.
We can change that version to 10 or 11 if you need with our new Webview.SetInternetExplorerVersion function. There we can switch FileMaker to use a newer version, e.g. version 11.
In a test on Windows 10, we get by default this browser version:
and with setting it to 11000, we get this:
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.2; Win64; x64; Trident/7.0; .NET4.0C; .NET4.0E; Tablet PC 2.0; .NET CLR 2.0.50727; .NET CLR 3.0.30729; .NET CLR 3.5.30729)
Just call the function once when running your solution.
