Backspace key does not work CRM 2011 UR17

We recently upgraded one of our Client’s organization to UR17. Everything seemed fine until our Development team noted that Backspace key does not work in CRM 2011 UR17.

This took us by a little surprise. On researching it a bit, it seemed we weren’t the only one to face this small but weird issue. So for all the guys who are scratching your head figuring out what’s wrong with your keyboard, don’t worry it’s not your hardware that is faulty, it’s the CRM.

Scope of the Issue

As far as we could test, this is only limited to Internet Explorer. If you access CRM from any other browser i.e. Firefox, Chrome, Safari etc.

So here’s how you can get it working again


  • Inside CRM web client, go to Settings >> Administration >> System Settings
  • Once in the System Settings, navigate to Customization Tab.
  • Under the Document Mode section, there is a little check box that reads Load pages in the most recent version of Internet Explorer.
  • Check this box and press OK button.
  • You are done, Backspace is working again now.

Document Mode Setting


Before you go ahead and make the change, don’t forget to read a small warning just beneath the Document Mode section which says “If you have form scripts or other customizations that require earlier versions of Internet Explorer, do no select the box.”

    Unfortunately, this just seems to disable compatibility mode which it seems we need to make our Document integration with SharePoint function correctly since CU 12. I really wish we could get everything to get along.

      That’s true, it’s not a perfect world.
      On second note, we actually stopped using IE because of all these silly issues. Firefox is what I would personally recommend here.

      Hope there are no customizations that you have done specifically for IE. In any case let me know how this works out for you (just in case you move to firefox).
