------- Comment #6 from cxh at eecs.berkeley.edu  2009-06-15 16:15 -------
I'm reopening this bug, there are problems with the code under:
* Windows Server 2003 via Windows Remote Desktop.  Java 1.6.0_04 and 1.6.0_14
  $PTII/bin/vergil, then File -> Open, then Cancel: HTML window scrambled,
  the links on the right of the welcome window are superimposed on the image
  on the left.

* Mac OS X, Java 1.5.0_16
  $PTII/bin/vergil, then File -> Open.
  Move the File Dialog and see that the links on the right are super imposed
  on the image on the left.

It appears that calling styleSheet.addRule("body {background: #939393;}");
is what is causing the problem.  The reality is that adding any rule
causes the problem on the mac

This happens for me as well, even when I actually open a model.

I also get the following exceptions:
