Does the problem occur with one or both external displays disconnected?

New Surface Pro 4 with Windows 10, MS dock, Dual Dell 23' monitors using Display Port cable and a wired mouse. &nbsp;At random, the mouse jumps to the upper left part of the screen, some circles appear and the user has little control over the mouse. At times multiple instances of a application open while nobody is touching the KB or mouse. &nbsp;I have tried with a wireless and wired mouse. Same problem happens.<br />
<br />
today an update to the surface 4 was applied (released Wed) that seemed to address this issue. &nbsp;Problem still occurs.<br />
<br />
Unit is new, has malware/virus protection local and on external filter.<br />
<br />
Anyone seen this issue or have ideas for a fix?

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.
