Since the advent of Internet Explorer 10, users of myFileGateway have noted compatibility issues with the web browser. Primary issues are that drop down menus do not function properly and various control buttons are unresponsive.
A workaround is to have the user enable the 'Compatibility View' function which Microsoft introduced into Internet Explorer. This then allows IE 10 and higher to display myFileGateway as if viewed in a previous version of the browser (IE 8). However not all users are tech-savvy enough to make this change or their corporate security may disallow it.
In the end, myFileGateway should be updated to be compatible with one of the more widely used web browsers which has been available since 2012 (IE 10's release date).
