Hello, just received my t904 today. I have been through these forums several times before but I don't think I've ran across anyone with my problems. After updating and downloading all the drivers and updates for windows 8.1 I find that the pressure sensitivity doesn't seem to be working as it should. The included stylus has great calibration, but it doesn't write without quite a bit of pressure. I originally thought that it was because of the Photodon screen protector I installed but unfortunately I removed it without any success. The pen reminds me of using n trig, or even worse where you can slide the tip across the screen with light force without making a mark. I find I'm missing many strokes that I've never missed on other devices (I've owned most of the big names). Anybody have any ideas? Would be much appreciated.
