When opening a .doc with lots of formulas, writer displays the rendered formulas incorrectly - they appear pixilated. Double clicking formula to enter equation editor renders the formula correctly. However, it is revealed (often) to be the incorrect formula. For example, I write " abs{ {-3} over {5} } ", save the document as a .doc, re-open the file and the formula in the equation editor is now " left ( {-3}over{5} right ) ".

Questions:

- Why is Writer consistently rendering equations incorrectly upon opening a document?
- Why is Writer changing formulas in the equation editor?

Thanks!
