Q: Sometimes CE acts like I'm still touching the touch panel even after I've released it. This behavior occurs more often in cold weather. We also often have trouble calibrating.
Check the touch panel settings in your ADSLOAD.REG file. Some older configurations use 175us for the PenDownHoldoffHns entry. Try the setting of 500ns as shown below. This works more reliably for most touch panels.
"SamplePeriodHighHns"=dword:c350 ; 5ms
"AdcReadHoldoffHns"=dword:6DC ; 175 us
"PenDownHoldoffHns"=dword:1388 ; 500 us
;"PenDownHoldoffHns"=dword:6DC ; 175 us
