I bought a Pen Tablet yesterday, so I'm gonna be able to make the lineart Digitally since now!! Of course I have to adapt myself to drawing in the tablet and look at the screen before upload some images made with it.

I've been testing it in CS5 (it's the version I have) and i have a issue with it. In the moment i open photoshop and start to draw, everything goes excelent, but after a time, Photoshop stops recognizing the device correctly and instead of make full lines, takes the point where I put the pen and the point where I lift it and it draws a line conecting them, a perfectly straight line. Anyone knows why this happens?
