k after several thousand words of pro capitalist ranting for my economics coursework i cant save my work to disk because its been made to be read only. i dont know why cos i havent done anything and i think it may be somethign to do with my computer running slower than Steven hawkins just now but how do i make it not read only so i can save it?

as u can imagine the prospect of not having backup for all this work isn't very nice and ironically a big part of he essay is about microsoft.
