Hi! This problem is probably one of the simple kind, but for me it's kind of tricky... What I want is to scroll a normal raster display in a window (in C code). To that purpose I think using ScrollRaster is correct...Next I want to add some new information in the now empty area. This goes fine, but the drawing is very slow and shaky... The question is then, is it somehow possible to, kindoff, draw outside the window first, and then scroll it inside the viewable part? I thought of making a dual-playfield, but my scrollwindow is lying on top of a backdrop window. Will a superbitmap be necessary? In advance thanx! Klavs Pedersen aggaton@freja.diku.dk
