so, im writing up my reports due for handing in tomorrow and having scan read the paragraphs, i discover that i need to add something in the middle of the paragraph. so i indeed start to rectify my mistakes only to discover that my new text is writing over my already sound work, which means i have to re-write stuff.

how an earth do i stop this? because it is getting annoying and making the work take longer than it should do.

or is it just because MS Works is a big pile of shit?
