I will try the .rgn drag and drop suggestion when I get home.

I am beginning to suspect that my touchscreen is not sensing my finger press or not properly processing said finger press. The touchscreen was working to put me in this state but now it is not. Or the device is not properly sensing the power button; it turns on the device but doesn't power it off no matter how long I hold it in position. So there is something awry that is preventing me from executing a pre-boot.
