I opened my word file and I saw that some of the equations had been changed to pictures, hence I can't edit them. why has this problem occured and How can I change them back to equation format?
The Equation Editor is supplied to Microsoft by Design Science Inc, makers of MathType, and they have a set of Technical Notes on their web site. One of them is likely to help: http://www.dessci.com/en/support/tsn/tsn103.htm
