Ok so, Tuesday I get home with my SP3, install all the updates + the N-trig drivers and then Gimp & FireAlpaca. No pressure sensitivity in either app. Got frustrated with it so I reset my device to factory settings and install N-trig, and FireAlpace. Pressure works! Finally! Now I can install those updates. After the updates(35?) no pressure sensitivity in FA. Well, this unit was defective anyway(hinge pop), so I take it back to the MS store and bring this one home. Again, I install N-Trig and FA. Pressure works. Install updates and... of course no pressure. I tried removing and reinstalling N-trig and FA to no avail. Pressure works fine in Fresh Paint. Not sure where to go from here. Anyone else having this issue?
