I guess the bitmap used in Sketchup is used in the msx-file and I tried several different bitmaps. Up untill now no B & W images, but I'll give it a try. That would have been the smart thing :-) Thx
but what to do if this is the case? A scene with just a cube on a plane is pretty straightforward. But it still doesn't work. What do you mean by 'a groupware'?
