Hi Gary: After installing the latest update to 10.5.8 on my desktop mac I solved my issue by going to the Safari Preferences and making sure "enable plug ins", "enable java" and "enable JavaScript" are all checked. After installing the latest update to 10.6.8 on my macbook pro, I had to do the same thing in Safari preferences, but I also had to open the Java Preferences in the Utilities folder and make sure that the "enable applet plug-in and Web Start applications" box was checked. That solved my issue of not being able to load pogo games on both computers (I'm sure there would have been other java related issues, but the pogo thing was the first thing I noticed". Hope this helps! blessings....
