Some more testing: The mousecolor returns the same RGB on Mac and Win. I need this for comparing each pixel of an imageData with this mousecolor. But when looping through the imageData of an image, the charToNum(char x of tImageData) returns a different value on Mac and Win. Up to now, it seems that the Mac value is always 30 less than on Win, same for R,G and B If this keeps constant on further testing, I can manipulate the values on Mac by this constant. But enough for today. Tiemo
