i received this reply from HTC support today:

Unfortunately this is normal functionality from the Sprint Touch Pro2 to return to the Today screen when the device is placed into Hibernation Mode. The only work around for this concern is to not allow your device to go into Hibernation Mode. You can also disable the backlight timer on your device. This option will dramatically lower the amount of battery life that is used on your device. Go on your device to Settings, All Settings, System, Power, and choose the Backlight Tab. From here you can uncheck the box to enable to backlight on your device.
