The value of the property 'MSOTlPn_ShowToolPane2' is null or undefined, not a Function object

Question

I have a problem with SharePoint 2010 and Internet Explorer 11. The following error message appears when I try to open the webpart menu.

In Internet Explorer 8 the wepart menu works as expected:

In Internet Explorer 11 the wepart menu fails to open:

...and the following error occurs:

The value of the property 'MSOTlPn_ShowToolPane2' is null or undefined, not a Function object

To open the site in compatibility view or Enterprise mode is not an option.

Compability view should be an absolute option when working with SharePoint 2010 in modern IE, why is it not so for you? — Robert Lindgren, Commented Nov 7, 2014 at 9:59
Because it's an demand from the customer to run "real" IE11 and SP2010. — Martin, Commented Nov 7, 2014 at 10:02
After trying to solve this and looking in blogs, I used Chrome to accomplish my task with success (Edit a page). — user38941, Commented Jan 22, 2015 at 18:38

You only need to add your SharePoint page to the Internet Explorer 11 Compatibility View settings:

In the master page "Edit mode" includes the javascript file called "ie55up.js"

Include the file "ie55up.js" in the Master Page using the <SharePoint:ScriptLink>

as follows:

<SharePoint:ScriptLink language="javascript" name="ie55up.js" OnDemand="false" runat="server" />

This solution is good, but not exactly right. When I try this the web part menu doesn't show and the edit page are directly loaded.
