I'm writing a paper using the article document class. I have an abstract at the beginning of the paper and this seems to mess up my formatting, for example, I have
\setlength\parindent{0pt}
With the abstract, the paragraphs indent, but when I comment out the abstract, it reverts to the formatting I want. There is other formatting, for example text height and width changes, which disappears when I include the abstract. Does anybody know what is going on?
