Hi, this is my first posting on this forum.
I have writing on MS Word, and suddenly I have some horizontal border lines appearing that I cannot delete. I don't know how they got there. I may have clicked some wrong keys while writing. Sometimes I type pretty fast without looking.


Anyway, now the cursor simply jumps above and below the horizontal line when I scroll, and will not eliminate the line when I select and delete, and I cannot move the line except by hitting Enter, which does not remove the line but simply lowers the line down the page. I have tried going to Format > Borders & Shading to delete them, but cannot.
Any advice please? Thank you.

FYI - Windows 7, Office 2003
