I recently posted a message about copperlists in KS 2.0. but I didn't
 receive any answers, so I'll try again.

For the display of a 'screen' which has some moving textbars in it, I am using
 2 copperlists. Every frame an interrupt creates the copperlist that will
 be used to display the next frame. This new copperlist is inserted in the
 system by:
 GfxBase->LOFlist = nextcopperlist.

This worked fine in 1.3, but it doesn't work properly under 2.0. since last
 message I have experimented a little and got the following results:
- The copperlists are swapped and used, the backgroundcolor changes
  to the right colours and the bars are in the right place.
- The text is not displayed, It looks like I am using a 0 bitplane
  display. (but I am not !!!!!!)
- When I swap the copperlists by putting them in COP1LC (reg 0x80 & 0x82)
  everything works fine. (except that my old view is gone forever and I have
  to reset to see my workbench again.)

What I wan't to know is:
- What changes where made to the copperlist organisation in 2.0 ?
- How can I insert my own copperlist in a system friendly way. ?

Hope somebody can help,
