AW: Is RGB on Mac something else as RGB on windows?

[Tiemo Hollmann TB]

Hi Trevor,

hmm, might be we are experiencing the same issue. The more I am testing, the
more I get confused what happens with the RGB on Mac.
Because I never would have thought that there could be an issue related to
this between windows and Mac this issue hits me at the latest stage in my
development process at the finishing tests close before release. Probably I
have to suspend my whole release plan now.
