heavy resource drain by InputPersonalization

I have always used a Wacom graphics tablet and Handwriting Recognition. Recently, InputPersonalization has been running much more frequently and for longer periods (1/2 an hour), using around 50% of my machine's resources, with the fan going into loud high gear. I tried stopping the process but it just comes back almost right away. In any case, I think InputPersonalization is essential for use with the Wacom tablet and Handwriting Recognition.

Any ideas about what I can do?

Added: InputPersonalization has been running continuously at 50% system resources for the past two hours. What is wrong here?
