The issue that you are seeing is related to the read order of RGBA date in MacIntel equipped systems. There is code that is internal to the filter that was expecting the byte order to read RGBA but we are being told that it is ARGB by the system, hence the color swap that you are seeing . This issue has been fixed with BCC 6.
I suggest that you upgrade BCC 5 to BCC 6 to take advantage of the fix for this issue, and if you upgrade you'll also gain an additional 15 amazing new filters as well as many other new features such as animated presets, faster filter renders due to enhanced multi-processor code and more.
