Long answer: You're probably using Internet Explorer 10, and you need to enable compatibility mode to get the MRH editor to behave properly. Here's how:

Enable Internet Explorer 10 Compatibility Mode

Some versions of Internet Explorer may require the browser be set to compatibility mode for the browser to work correctly with all of the MRH post editor's features.  Internet Explorer 10 on Windows 7 or Windows 8 requires that the compatibility mode be set.

Internet Explorer 10

By default Internet Explorer 10 in Windows 8 does not run in compatibility mode.  If the compatibility mode is not enabled, you will not be able to enter carriage returns or line breaks into your posts.

To enable the compatibility mode for Internet Explorer 10, follow these steps:

Windows 7 users start at step 2.

1. Windows 8 only - From the Windows 8 start screen select the Desktop.

   
    

2. From the Desktop launch Internet Explorer 10.

   
    

3. Press the Alt key on your keyboard to bring up the top menu.
    
4. Go to Tools | Compatibility View settings

   
    

5. Either
   • Add model-railroad-hobbyist.com and mrhmag.com to the Compatibility View websites
     or
   • Select Display all websites in Compatibility View

     
      

6. NOTE: enabling the compatibility mode using either option will correct the MRH website posting issues.
