Problems with Sun 3/60 with color buffer

[iccad]

We have 2 Sun 3/60 with P4 color frame buffer running Sun OS 4.0.

 (cgfour0 at obmem 7 csr 0xff300000 priority 4,
  bwtwo0 at obmem 7 csr 0xff300000 priority 4,
  bwtwo1 at obmem 7 csr 0xff400000)

The Sunview program seems to have a s/w bug with this particular
configuration.  If you get into Sunview, pull down the menu, select Exit
Sunview, the cursor (arrow) will use the background color (i.e. white, or
shaded, depending on where it the cursor is), instead of black.

However, if you select Cancel, and then try to pull down the menu, select
Exit Sunview again, the cursor (arrow) will have the black color.  It
seems there are some initialization problems with the color buffer.

Are there anyone has the same problem?  Would anybody from the Sun like to
comment on this?  Thanks.
