Finally have my Surface Pro 128 and love it so far. One issue though... when I have the Type keyboard attached and the Surface Pro is plugged into its charger, the cursor moves all over the place on its own as soon as you put a finger on the touchpad. You don't have to even move your finger... the cursor just shoots all over the place. I spent an hour and a half on the phone with Microsoft and first they heard of this. What is weird is that as soon as you unplug the charger from the tablet and its just on battery, then everything behaves as it should. Cursor stops jumping around and only moves when you move your finger on the touchpad. Microsoft couldn't figure it out and even had me re-load the system. No go. Exchanged the unit today at the MS Store and the new one is doing exactly the same thing even with another new Type keyboard. I'm totally baffled. The girl I dealt with at the store did mention that someone else returned their Pro last night for exchange for the exact same reason. Is this some new problem that is starting to show up? Thanks in advance for any suggestions and also curious to hear from any others that have seen this.
