Thats how I want it to scroll up but here is what should happen. You walk up to an npc_merchant to buy some of your favorite pumpkin flavored gatorade. You right click on the npc and your first line of text will start at lets say y = 10. then the next line y = 20 and the next line y = 30 and so forth. Then when line 10 is reached, then ONLY line 10 will be filled with the new text and all previous text will continue to scroll up with every new line of text in line 10. So for any line of text in line1 will essentially just disappear and be lost for good. This is just a text encounter window for npc's and maybe combat too. After you purchase that yummy drink you walk away window closes and all text is lost for good.
