What to do when Word crashes?

"Such is the nature of the beast that sooner or later Word will crash. When you restart, Word may try and recover the document you were working on, but this is a bit hit and miss, so don't rely on it. Configure Word to create a backup file - and save often. It is good practice to drill CTRL+S into your brain and apply it every time you pause for thought. Then when the wheel comes off, you don't lose too much work." gmayor.com
