hi alex, thanks for the reply- i have an example at
http://www.andersonwebstudio.com/languagechecker.html (view source enabled) this is an RTE with an added language checker to look for bad words- the word 'bad' is one of them so if you type that in a sentence on the left side you will see it turn orange when a textrange gets created and styles applied. when you mouse over that word i want to fire an event, which is not firing.
