I'm seeing this across the board. That is, on too many Windows 7 laptops. There is something going on behind the scenes it seems and here we are thinking it's not a maker issue but something Microsoft needs to address.
If MSFT follows their usual game, they will never fix it but issue a new Windows.
Iam referring to the Samsung Series 7 slate pc running Win 7 professional. The screen sometimes suddenly stops responding to pen input but continues to respond to finger touch. I have calibrated (and recalibrated) the screen with the pen but the problem persists. To get back to pen input I must refresh the screen (go into and out of sleep mode, for e.g). The problem can occur whether I am browsing the web or using offline app. Does anyone know why this is happening?
