Repeating in lexicon editor

[francesca]

I am having an easy time getting the voice to say the word correctly in the lexicon editor. But my problem is the word repeating when I try to enter a new word. For example, I can make it pronounce "Madison" correctly, but when I enter a new word, "Montreal," the lexicon editor still says "Madison." My only idea is to open a new internet window and start again. Any suggestions/ideas?
