I've just upgraded from jre1.6.0_03 to jre1.6.0_04 and I'm having difficulties interacting with Calendars that were working in 1.6.0_03.

Has anyone else upgraded to jre1.6.0_04?
Are you also having problems interacting with Calendars?
I know I have Silk Test configured correctly as all my other applets seem to work ok.
