Windows can change what device the touchscreen controls. Often the screen being controlled by touch is defaulted to the main display & not necessarily the correct one. You are able to update which screen the espressoDisplay is controlling by
1 - Go to control panel
2 - Type in the search in the top right "Calibrate" it will then bring up Tablet PC settings (Calibrate the screen for pen or touch input)
3 - Click Setup
4 - If the writing is on your espressoDisplay simply touch the screen. If the writing is on the wrong display just press enter. (this should move the writing to your espressoDisplay.)
5 - Once its come up on your espressoDisplay simply touch the screen and then press enter.
