before i begin, thanks to: jawaid bazyar andy stadler jim murphy todd whitesel julian pugh for their help with the offscreen grafports. after many hours laboring at my computer i finally figured everything out. one thing i didn't state was that the reason i drew from window->offscreen grafport->window was to test if the updating to/from the offscreen grafport was working. while the update was slow, i took into compensideration the fact that the real speed would be 1/2 this. yet that is still too slow. i'll probably write my own ml routines to update both the onscreen and offscreen grafport. i don't think it will be too hard to write a routine to copy the portRect of the offscreen port to the onscreen one as there is no horizontal scroll bar which certainly makes life easier. anyway, if anyone still doesn't understand how offscreen grafports work post and i'll upload my source code then others can pick at it :) albert
