I'm developing a game engine on top of LWJGL and I've added a couple of functions for changing the icon, which essentially consist of converting a BufferedImage to bytes and then sending that to Display.SetIcons(). The code worked absolutely perfectly on linux, but when I sent all of my code to my desktop (which runs on Windows XP) and recompiled, the icon code didn't work. SetIcons() is reporting one used icon, but the icon on the window is still the LWJGL logo
what is the size of your icon?
