Write leaves gaps in text

Writer leaves blank spaces in texts. A space the length of a paragraph will appear, and I can use Del at the end of the last word above or Bksp at the beginning of the first word after with no effect. The cursor simply skips to the previous or next paragraph. I can try selecting the blank with my cursor, but it does not show that it is selected. I use “Clear direct formatting” with no result.
Has anyone had the same problem? Any help? I’m using version, Win 7.

Please edit the question to include an example document or screenshot for clarity. Also, try turning on Nonprinting Characters (CNTL+F10) to see if that reveals anything. Thanks.

I saved the doc and re-loaded it and the gaps disappeared. Easy solution!
