Thanks to those who responded to my question.
I must be dense, but I'm still not getting it. I just can't figure out
why the code below doesn't work. There's not much to it, just a block, a
background, a light or two, and the required objects for it to show up
on the screen. (I've even removed all applet functions)
Can someone please look it over and tell me where I've gone wrong?
