Twice now, I've had large Excel files go kablooey, getting this error message:
"Excel found unreadable content in filename.xls. Do you want to recover the contents of this workbook?"
The damn program was able to read the content just fine yesterday. I have a backup, so I'm not concerned about losing the data, but does anyone know if this is a compatibility issue (the program's in 2010, and from my laptop, but my office computer has 2007) and how to keep it from happening and fix it when it does?
