Hi, I started using 'MPinitialisation' to store some global variables. Much easier than passing them over and over again to MP macros. Sadly this way is inaccurate with the unit 'px' (no such problems with 'pt'). See attached example. The frame gives the exact size, showing that the MP graphic is 'out of bounds'.
