yesterday i bought a tablet for drawing and connected it to my computer...the problet is that I can not draw in photoshop elements. everytime when i want to draw a line, I first have to doubleklick with the pen. If i try to draw normaly it opens the brush optioins. I have already checked all options but couldnt find the mistake. I adjusted that pen klicking is the same as the left mouse klick...actually it should work normaly..?
