|Is this a laptop? If so, adjust a few options ...|
Click the start button with the windows logo on the left side of the screen at the bottom.
Choose control panel from the left list. One left mouse click.
If you do not see three lists of icons, look at the right-top portion of the window for the word category. Click the little downward-facing triangle, and choose your icon size. I like small icon. Most of the icons will fit in the three lists easily.
Choose the icon with mouse.
Click the device (settings) tab.
Click the settings button.
On the sensitivity option, click the plus sign.
Highlight the palm check (click), on the right side move the slider to the needed level.
Highlight touch sensitivity under the sensitivity heading too. Move the slider here as well.
If this is not a laptop, seek out new drivers from the manufacturere. Run Windows updates.
