What do you mean by "even the paragraph setting say so"? If the paragraph
line spacing is 1.5, then it's not single-spaced. If the paragraph claims to
be single-spaced, then check to see whether there is any Before and After
spacing. What style is the paragraph in? Is it possible that the font is
Superscript or Subscript?

I encounter a special document which single line spacing appears as 1.5
line,
even the paragraph setting say so. The vertical alignment is Top.
After changing the fonts, the problem still persists.

If ctrl+A then copy to a new document, the problem still exists. The
problem
disappears if the last mark in the document is NOT copied. What is the
problem? help!

The boss owns this document wants to know the cause..., not only the
solution,
help!
