Word auto-hyphenates the word "although" improperly. It puts the hyphen between the "t" and the "h".
This frustrating problem apparently existed in Word 2010 as well.

How do we get Microsoft to correct bugs like this? Ctl-hyphen is not a solution -- only an occasional workaround.
MS - don't make it hard to identify and report bugs. These types of problems need to get fixed!
