First of all, thank you very much for the reply. MapView tells me the correct coordinates of the center of the screen. When I move my mouse left, it will tell me for instance 9 7. Then when I move my mouse to the right it will tell me 10 7. No matter how far I move left or right 9 7 and 10 7 will still be in the center of the screen like my mouse is there. Suppose I go to 12 7 and put an ocean or something there , it will fill 10 7 or 9 7. No matter where I put it, it will change only the center tiles unless I move the whole map to whatever tile I want to change. I changed the window size and all zoom levels and it still doesnt do it. My graphics card is up to date so I might revert back to an older driver to see if that does anything. Like I said, MapView works on my other computer, so I can still use it fine. I was just curious if I was missing something. I hope that makes sense, its hard to describe without actually showing what it does.
