Hey guys... I've been using my tx2000 with a Grip Pen for a while now... It works great, but for one single issue. I have the second side button on the pen set to "middle mouse button" which I really need. When working in Blender 3D, at times (actually, way too often) that button stops working. If I then lift the pen off the screen far enough to deactivate it... it resets or something and it works again. If anyone has any idea what could solve this, I would really really appreciate it. I did lots of searches, but haven't been able to find anything at all.
