Closing Word Highlighting Dialog leaves Highlighting Start dialog hanging

If you click on a word in Word Highlighting to adjust it and then close the Word Highlighting dialog the Highlighting Start dialog remains hanging open and the "Tap to Set" button doesn't work.  Suggest adding a cancel button to Highlighting Start dialog in case a bad number is entered.  Pressing the "Done" button on the Word Highlighting dialog should close all child windows with a warning dialog if value was changed.
