Motorola Xoom :: Degrading Performance With Handwriting Applications?

I can't remember where I saw the comment, but another Xoom user mentioned that his handwriting application(s) seemed to degrade in performance the longer he used them (per reboot, I believe). Until today, I thought I was imagining it, but the same thing seems to be happening to me. I was taking notes with Writepad and about one-half hour into the meeting I experienced significant lag between strokes of the stylus and appearance on the screen, and I needed to revert to the keyboard. It's happened with other handwriting applications as well.
