The problem with the feather count. tablet

Tablet model: WACOM Intuos Comic Pen&Touch Small
The problem is that when you press the pen on the tablet computer automatically interprets the movement as if I wanted to press the right mouse button. Ie usually to simulate pressing the right mouse button takes some time to hold the pen in place, and then around the cursor a circle, and when it is closed, is click, right-click. And while it appears I can't make small movements with the pen, only to abruptly move him to cancel the click. This is usually not a hindrance, because to begin click, need not to move the pen for a while, and because of this I can take a short and quick strokes, or some rounded and small, not afraid of what will happen click. But now the click is immediate, and because of this I or push the right mouse button, or do a sharp and fast long movement. Because of this, I can't draw any smaller/rounded lines, because in the beginning, the cursor first is some time on the spot, and then abruptly jerks to the side. What to do with it?
