FYI.
During the latest months, there have been several postings on problems running Windchill wizards with updates higher than Java Runtime 6 update 7 and I have experienced problems myself.
I have for the last week been using Java Runtime 6 update 12 without any issues so far. I downloaded it directly from java.sun.com as the updater still suggested update 11 last week.
