Thank you for the info. Unfortunately, Doug Johnson's reply never
made it to me or I managed to delete it before reading it.

I will look forward to hearing of a fix or work-around.

This is a known bug involving S-PLUS 3.4, Solaris 2.5 and Common Desktop
Environment:

"Many users have reported that 'spin()' and 'brush()' do not
erase points when the axes are rotated - leaving a blur in
the spin window. All of the users who have reported this
problem are running S-PLUS under Solaris 2.5 and Common
Desktop Environment. If they refresh the screen, all of the
old points get erased, and the point cloud is displayed
correctly."

Unfortunately, we do not yet have a workaround or a fix. I have linked
your question to the bug report in our database.

I hope this helps. Please contact us here at technical support again
if you have further questions.

We have confirmed this problem on Ultrasparc 1 3D configuration and the
