Robohelp 9 and IE 11 compatibility - Blank web page issue

For one of the .NET applications, we have created a context-sensitive webhelp using RoboHelp 9. When we open the application in IE 11 and click the Help button, it is opening a blank web page and then the Help opens in the new tab. Even after modifying the browser compatibility settings, the issue is not resolved. Has anyone come across this issue? Any help will be appreciated.
