macropod,

many thanks for the updated macros.
But still I get the same error 5610 even on very simple texts...

In the text below it hightlights "republic" which is not dublicated.
The check proceeds up to the first word "states" and then I get the error...

"The U.S. is a federal republic comprising 50 states and the Federal District of Columbia. It originated in the American Revolution, the successful rebellion of the colonies on the eastern coast against British rule in 1775 - 83. The original 13 states that formed the Union drew up a federal constitution in 1787, and George Washington was elected the first president in 1789. In the 19th century the territory of the U.S. was extended across the continent through the westward spread of pioneers and settlers and acquisitions such as that of Texas and California from Mexico in the 1840s. After a long period of isolation in foreign affairs, the U.S. participated on the Allied side in both world wars and emerged from the Cold War as the world's leading military and economic power"
