Similar story with gene names.
I have a few genes such as SEP7, SEP10... if the file is touched by  
Excel, they're gone!
I can avoid using Excel, but I can't be sure that when I receive a  
file from somebody else it will not contain that sort of errors.
The first thing I do when I get a new Office version is disable all  
teh automatic BS that it tries to do to "help" you. Incredibly, the  
behaviour with dates in Excel cannot be disabled!
