Mouse jumping around screens. Lenovo Yoga 2

[FlexJargon]

I have the Dynadock PA3927U-1PRP connected to a brand new, updated Lenovo Yoga 2 Using most current drivers on all. I have the identical set up at home and in the office. The mouse will suddenly begin jumping around the screen taking the system focus with it and clicking buttons.

I was using a Sony VAIO for the last 2 years without any problems. However, both Lenovos have the same problem. I've tried using a standard USB corded mouse, Bluetooth mouse and lastly a Logitech K520/M310 wireless USB combo. I've tried the 2.0 and 3.0 docks on both the laptop and the Dynadock with no change. I'm using multiple apps all day, Excel, Firefox, Thunderbird, G-Talk, Skype, Itunes, Word, Acrobat reader, PowerPoint to name a few. I have not been able to notice pattern based on the apps open.

Help?
