After trying to sort out my totally unresponsive touchscreen on the POV Mobii for over two weeks and having tried every re-calibration tool and utility available, P10 Test rom, updated POV Mobii rom, updated Viewsonic rom and the firmware update and configuration files kindly provided by Richard Lea I have finally accepted defeat and handed back my POV Mobii tablet back to the supplier and got a full re-fund (he did not have any untis to replace).
Richard Lea is right (as I was sure he would be) that if your have the 99 firmware, it is corrupted and can not be either re-calibrated or updated. Sad, but true. Therefore, if your tablet is in warranty, get it replaced or re-funded. If it is out of warrantly, get the touchscreen replaced by the kind man, who offers this service.
