When using Internet Explorer 11 in eB WEB 'File drop zone - Turtle' is missing for unapproved Documents but it's visible in 'Create New eB Object' window and Documents containing files missing 'Get local copy' option but from Edit view actions launch, upload or download files can be done.
ActiveX does work only on Internet Explorer but as Internet Explorer 11 doesn’t identify itself through User-Agent string as IE (user-agent string of IE11 - Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko) it’s being treated as browser non supporting ActiveX.
Open Internet Explorer and navigate to Tools> Compatibility View settings
In 'Compatibility View Settings' add required websie. After taking this step IE11 will 'identify' to this webserver as IE8
