Hello All, I have a program that I wrote that draws a lot of triangles via AreaMove/Draw/End calls. This program worked fine on my Amiga 500. When I got my A3000 I thought I would recompile it to take advantage of the math chip. But now it doesn't draw anything! I am pretty sure the bug is taking place in the Area calls, as if I replace them by Move and Draw I get a correct wire frame picture. Has something changed in order to use these calls? I have 2.03 and am using Aztec C 5.0d. Also, AreaMove & AreaDraw are returning 0 (no error). According to the 1.3 RKMs AreaEnd also returns a value, but why does Manx's functions.h have AreaEnd prototyped as returning void? Any advice is greatly appreciated. Brian
