I have an application which has its icon set to an .ico file which contains the 7 necessary icons sizes for XP and Vista i.e. 256x256, 128x128, 96x96, 64x64, 48x48, 32x32, 16x16
Icons are displayed correctly throughout all XP and Vista screens but when using alt-tab to switch applications, the icon is not shown correctly. It is pixelated and the colours are all wrong.
What do I need to do to ensure it is displayed correctly when using alt-tab?
