No answer here yet has addressed this individual's question. He's asking about the auto-generated horizontal lines. I found a procedure that works:
1. The line is not deletable because it's technically not "selectable," because it's an auto-generated "border" that Microsoft thinks is a "feature." :) They add it if you string together a handful of dashes or equal signs. To get rid of one, do not try to select (do not try to highlight) any line. Instead put the cursor on the point immediately BEFORE the auto-generated line.
2. Click on the Format menu...go to the "Page Border" tab. (If the Format menu is not available, you're using a version of Word that hides it somewhere else...in this case select the "Page Layout" menu, find the "Page Background" portion of the ribbon, and click on "Page Borders." Then go to the "Page Border" tab.)
3. Select "NONE" on the left, in this "Page Borders" tab.
4. Go to the "Borders" (which means "Tab Borders") tab, and again select "NONE."
This should remove the auto-generated border. If it doesn't go away, try these additional tricks:
a. Select any text immediately before or after the line.
b. Find your way to the "Borders and Shading" menu, as described above.
c. Before applying a change, try configuring it to "Apply to" the option "Text" (lower right hand corner of the "Borders and Shading" dialog box). Then do the changes listed in Steps 1 to 4 above.
d. If it had already been set to "Apply to text," then try applying it to "Paragraph" instead. Then do the changes listed in Steps 1 to 4 above.
These steps should make the line disappear.
I hope this helps; I've had the same problem for years, and now finally have a solution.
