windows ce - How to ignore 1st touch event when screensaver is enabled -


on our win ce 6.0 device (x86 platform), screensaving enabled using powermanager useridle timeout:

[hkey_local_machine\system\currentcontrolset\control\power\timeouts] "acuseridle"=dword:3c

my assumption is, graphics driver (intel iegd) listens event , turns on/off backlight accordingly.

the problem is, when screensaving enabled (backlight off), 1st touch event utilized windows system. in other words, user touches touch screen while backlight off, , accidentally/blindly triggers action on running application (eg press buttons...).

we don't have sources touch driver (tsharc usb), changes can't made here.

are there other ways discard 1st touch event while backlight off? place at?

thanks in advance / suggestions. regards, timm
