I have an Adesso Z12 Graphics Tablet, and something seems to not be right with it. The tablet recognizes the fact that I'm trying to draw and do things on it, but the pen skips to somewhere else on the screen, and when it does what I want it to do, it selects the area around it whenever I move it. For example, if I clicked on somewhere on the webpage and moved the pen, it would select a whole block of text.
