Touch IR pointer not working correctly in portrait mode

[kylekc@umich.edu]

I'm super excited that touch IR pointer support is here, but unfortunately I can't get it to work correctly when playing in portrait mode. It seems to work fine in landscape mode using the default settings, but not in portrait mode. Left-to-right motions seem to work fine, but up-and-down motions are not. First, I have to touch slightly above the actual display screen for it to register my touch inputs at all. Second, very small motions up-and-down seem to move the pointer a lot, which is not the case for left-to-right movements. Hopefully this makes sense, but basically, if I touch just slightly above the display screen, the pointer registers at the very bottom of the screen. If I move my finger up just a few millimeters, the pointer moves all the way to the top of the screen. I've tried changing the width, height, and center settings but none of them seem to help. Is there some combination of these settings I haven't tried yet, or some other setting I'm missing? Or does that feature simply not work in portrait mode yet? Any help is appreciated!
