Hi, you don't know why ? In versions before 6.0 Show[] and all ploting functions had a side effect that cause the Frontend to display the graphics. This was unique to graphics objects because a=Expand[(x+1)^100]; b=a; would display nothing, only a=Expand[(x+1)^100]; Print[a]; b=a; would do that. But in versions<6.0 a=Plot[(x+1)^100,{x,0,1}]; b=a; would display a graphics. This side effect is droped in version 6.0.
