If you highlight (or select) text (or click somewhere else then) in the sample PDF document of your current Groupdocs.Demo.Annotation.CustomGUI example project, you will get an error with IE11 browsers.
Error: Unable to get property ‘length’ of undefined or null reference
It works fine with Firefox and Chrome.
I get this error in IE 11.0.15 and 11.0.25. So it could be a generic IE11 problem.

Hi Phil,
Thank you for your inquiry.
Text Selection is working fine in Next Generation GroupDocs.Annotation API. Our Next Generation APIs are decoupled from Web UI and made for more flexible development, please give a try to our latest API . We have also published old front-end on GitHub as open-source which is compatible with GroupDocs.Annotation for .NET API 3.x.x or higher.
Please find below some useful resources to quickly get started with GroupDocs.Annotation API.
