Touchpad and touchscreen both shitting out at the same time seems to point to related services stopping for some reason... I don't have a touchscreen, and I'm not Coda, but, hm...

If you open Task Manager and go to the Services tab, do you have "SynTPEnh" or any other service that could be related to touchpad/touchscreen?

If you do, perhaps you can scroll to that service before the touchpad/screen stops working, check to make sure the services are running, then go to FB (or whatever else seems to break the touch functionality), then tab back to task mgr to see if the services are now stopped.
