Don't worry ! You have to change your Color Depth of your Windows Screen. (In your Windows Display properties Menu) Maybe you are in 16 bits(default) You should use 24 or 32 bits (it depends of your video card I mean) I had the same pb with Vue 4.06. But no-one at E-on can explain that... Because they don't have such pb (And so many Vue Users..) They told me to use 32 bits Color depth.. and it's working.. Denis
