Why when I paste a document into word, sometimes blank space appears after a paragraph and I cannot delete the blank space in order to bring the text on the following page back? It just won't let me delete the bland spake between the 2 paragraphs.

Then I will do things like press enter at the beginning of a paragraph to move it down one space, and it will only jump the paragraph an entire page instead of just doing what I am wanting .... which is simply moving it down one space. It seems to have a mind all its own. So frustrating!
