oh come on man. While I AM glad you can still buy this, they have already made a ton of money of dopus. They stopped updating it ages ago. I think you need to lower the price or add new features if you are going to sell this old stuff. Frankly I agree just make it PD, there are not enough folks that can or will pay premium price for out of date software. Since we supported dopus back in the day now would be a good time for them to give us something back.
