Consider the following scenario:
You have a Windows 7-based computer that is connected to one or more touch screens.
You put the computer into sleep or into hibernation.
You resume the computer.
In this scenario, one or more of the touch screens do not work correctly. This may include the following symptoms:
On a system that has two touch screens and no keyboard, touching the keyboard screen causes the mouse to move on the other screen, rather than on the keyboard screen.
The mouse cursor does not change from the mouse cursor to a dot cursor when you touch the screen.
To work around this issue, restart the computer.
