problem solved! somehow it change to full screen mode, what i did was:
installed again the fresh kro client from ratemyserver.net, and before i update i change the configuration setup to full screen 1366 x 768 resolution and thats it, my old client is full screen 1366 x 768 and also my newly fresh installed client too. thanks
i already did that but nothing changes, im a noobie on this ragnarok but as far as i know i download eathena, 3ceam server, and kro client? and updated it, i downloaded on ratemyserver.net
