An associate of mine is having a problem with excel seemingly not saving files correctly.

Whats happening is that she will make changes to the file she is working with (these are simple field data changes no macros or formulas, just entering and deleting) but when she re opens the file all that she has deleted is back and all that she added is gone. She IS saving after making the changes and before closing excel at the end of the day.

I've had a look at the settings, tried saving as a new file, the HDD is no where near full and the machine she is running iton is not connected to our LAN

If anyone can give me some pointers it would be much appreciated.
