For some weeks now I can see 2 mouse pointers when I move the mouse
around below scan line 210-211 on my (PAL) screen. I see the
second pointer following the first one when I move the mouse.  Also,
sometimes, when switching between screens (with A-M, with or without
mouse accelerator, like DMouse), I can see the mouse or the "zzz"
pointer hanging around on a screen, while I still have another mouse
that I can move.

My Hardware is:
B2000 PAL ReV 4.3, Bridgeboard A2088, Kronos controller with 80MB Quantum,
Supra 2MB RAM, Kickstart 1.3 (V34.5) installed 1,5 years ago, Big 1MB
Agnus installed a couple of monthes ago, following Dave Haynies
instructions here on the net:

>The 1 Meg Agnus works in all B2000s.  There are two or three jumpers to change
>to install it correctly (J101 is moved, J500 is removed or cut depending on
>how your board was assembled, and J102 is cut if you want to come up PAL
>instead of NTSC).

No special software need be run, the problems appears even with my old
WB 1.2 disk ! It must be either a hardware or a ROM bug.

I don't think that the problems began as soon as I installed the new
Agnus, but the installation has been the last modification I made to
the hardware.

Any help appreciated. This pointer duplication is rather annoying!
