When i want to add a few words to the middle of a sentence, the words in
front of my cursor are deleted as I type the new words in. This only happens
every so often but every time it does I find no cure and resort to restarting
me computer. I've looked through the help wizards and all that jazz but I
can't find anything related to this. It's really ****ing me off. I've got
Word 2003.

Thanks
