though this still happened to me without a modded file, i now have a modded file. with Rei's minimap and the texturepack fixer. default size of the game window. http://prntscr.com/1hcm7t examples of the window being expanded - http://prntscr.com/1hcmikhttp://prntscr.com/1hcmm5 . i then click out of Minecraft window, to click for example, facebook or something else, later click the Mc window again to continue playing and it is back to default size. is there a fix for this? -please message me if the links break or dont load-
the new launcher is reseting its own size after expanding it without maximizing.
