When using Microsoft Word, if you draw a line that extends from inside a header/footer to the body of the document, you will see a solid black line located at approximately 4.17 inches from the right edge of the page when text is typed beside the line. This is more likely to occur when the zoom is greater than 100 percent.


This behavior is caused by a problem in the Windows NT multilayered driver interface. NetMeeting calls this interface with its MNMDD driver to share applications and collaborate.


To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:
152734 How to Obtain the Latest Windows NT 4.0 Service Pack

You can work around this problem by not using the multilayered driver interface. Perform the following steps to disable the NetMeeting application sharing and collaboration:

  1. In Control Panel, double-click Devices.
  2. Click MNMDD, click Startup, and then click Disabled.
  3. Click OK, click Yes, and then click Close.
  4. Shut down and restart your computer.


Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
