I recently noticed that occasionally my intuos2 will start producing slightly wavy lines. whenever that happens, I can try drawing with a ruler, and the line is still crooked. searching on the web it seems some people have the same issue, but no-one seems to know what the problem is. it comes and goes, at first I thought maybe my motor control went out the window I emailed Wacom tech support but it's been a couple of days and still no response. anyone who had this problem ever figured out a solution?
