Thanks to Mayrie, Gary and Barbra for their responses to my problem opening .rtf files in Kurzweil v12.04. It turns out that the culprit is not Kurzweil but microsoft security essentials. I still haven't been able to find the problem, but from now on, if I want to open an .rtf file I will have to go turn off security essentials. And, as Paul Harvey used to say, "that's the rest of the story."

It gets to page 43 and flashes one of those really helpful messages "an error occured while opening the document." I'm not trying to solve the problem--I have an excellent work around thanks to Mayrie--I just want to know if it's just my system, or are others having the same problem? Of course if you have a quick fix I wouldn't mind trying it. Thanks, Bob
