Does anyone else have an issue with the G903 skipping? When it's plugged it, it's great. It tracks great with no issues. When I am using the light speed dongle, it starts skipping. Like the cursor will track then skip across the screen very frequently. I've had it plugged into the back of my desktop (desktop oriented sideways) with the back of my desktop less than 3ft straight in front of the mouse. Also had the dongle plugged into the bottom of my Samsung G9 Odyssey display. they both act the same. When the wireless dongle is in the adapter and sitting like 6in from the mouse it tracks great though.
