tablet

SOLD: 115$ shipped Lenovo Tab 4, 10.1" Android Tablet, Quad-Core Processor, 1.4GHz, 16GB Storage with blue-tooth keyboard Its in great condition. Just used as a display and I decided to go a different route. Together, these items are 165+ new.

I have a tablet and touch laptop. Both will not recognize trying to move sliders (in graph mode) or let me move things out of the 'lock' section. Is this a know issue or is there a setting i need to adjust? Thanks
