When you open it do you copy it over to your PC first or do you open it from
the thumb drive? If you open from any removable media ie thumb drive,
floppy, CD you are suseeptable to corrupting you file. May work many times
but there is always that one time that it does not. Try to find a copy of
your work and always drag it over to your hard drive first, save it when you
are done and drag it back to your thumb drive for transport.
