abailie,
We have found there are some issues with larger displays (10.4" and 12.1") with the LH7A404-11 Windows CE touch driver. We are working on this driver and hope to get an updated release soon.
If you want to keep posted on the status of this driver, please email
platformsupport@logicpd.com. Once we have released it, a blog posting will be made and the driver will be posted.
Thanks,
Mike
