Re: PRException again

Excellent piece of detective work!

Yes, we have anti-aliasing turned on -- we override the

     public void render(Graphics g)

method on OMGraphic.java in order to turn anti-aliasing on. All makes sense.

I wonder how many other undocumented exceptions exist in the java world?

thanks again. not sure to how correct for this. we might catch the
exception and pop-up a dialog saying "you can't zoom this far".
Once this exception is thrown, all kinds of bad things happen.

thanks again
