No backgroundcolor

[R. Hillen]

Hello list,

I wanted to make a green rect with a red edge, so I wrote

       create invisible graphic
       set the style of it to rectangle
       set the rect of it to 20,20,50,50
       set the foregroundcolor of it to 255,0,0 --RGB_Color
       set the backgroundcolor of it to 0,255,0 --RGB_Color
       set the linesize of it to 2
       show it

I got a white rect with a red edge. Why?

May  you help?

Richard.
