How to recover “lost java”?

I used to play bridge on Pogo every day for several years both with Panther and more recently with Leopard. Earlier this year after I upgraded to OSX 10.5.2 I started having problems and despite going to Pogo help several times and also posting on this and other forums the problem persists. I have a feeling that there is some bug in the Pogo game Applets, as sometimes if I log out and then log back in I am able to play. Also clearing the Safari Cache as well as the Java caches sometimes works but not always. Something has changed and I am beginning to believe the problem is with Pogo. I only hope someone will be able to put a finger on the solution.
