I occasionally use Squeak 2.7 on a Sun running Solaris 2.6.  I get a
primitive failed error when running in morphic.  The error is
repeatable.

If I move the cursor over one of the preferences in the preferences
window or I move the cursor over a halo the error occurs.  The error
is the result of trying to show a balloon and it occurs in
BalloonEngine>>primInitializeBuffer.

Is this a known error or might it be an installation problem?  Does
anyone have a fix?  I haven't seen this error on my Mac.
