You did understand my message correctly. I'm confused by both you entries StatGirl - one sounded like you got my suggestion and the other didn't!
Most importantly, the fix did work.
*To be very clear, this exactly what I did...*
1. Got to
http://support.spss.com/
2. Having registered first, click on 'Sign in now!' and logon.
3. Click on 'Submit a case' in the top left hand corner.
4. In subject field put something like +'PASW18, Apple Java 1.6 R3 Problem'+
5. Fill in the form and put something like this in the +'Description of Issue'+ box:
+'Since Apple updated their Java version this week, I'm no longer able to draw graphs within PASW18.+
+Please work with Apple to determine the incompatibility - it has been identified by a number of other users and logged on the Apple discussion forum.'+
6. Wait for the case to be actioned and you'll get an email back from SPSS when they've respond.
7. Follow the instructions they provide.
Good luck!
