ok in TouchPanelSetmode on msdn they said that:
Remarks
High and normal IST thread priorities are read from the registry. The high priority value is set by HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Touch\HighPriority256. The normal priority value is set by HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Touch\Priority256. By default, high and normal priority settings are both 109.
SO this mean that with Have first to Disable Panel, Set both Registry To lower Priority and SetMode to normal Priority and low sample rate (TPSM_SAMPLERATE_LOW) then re-enable Panel, and this should be OK.
Ok i try to Link touch.dll, i'll tell you more!
