I was just working on a document in Word 2003, and suddenly it is "locked for editing by Lisa" (me). I can't edit or do anything with it - it's read-only.

I was trying to mess around and figure out how to unlock it, and i also got an error message: "Changes have been made that affect the global template, normal.dot. Do you want to save these changes?"

Would really appreciate some help!! Basically I just need to make sure I don't lose the changes made to my document, because I had not saved it before Word locked. I can't even close the window.

In order to save my work, I tried right-clicking on the document in windows explorer > save as, and saving it in a different name in an attempt to save it - but it has NOT saved the latest version!
(I sent this saved version to a friend who sent it back by pasting it into an email so i could check whether it had saved the latest changes - because Word is completely locked!- and it has not saved them)

So please, can anyone advise how to either unlock without losing changes made to my document, or how to save it!
The most important thing is I just need to make sure the changes I made to my document are not lost!!

Thanks in advance!
