I have Win XP SP1 and the latest sun-java and play
games on pogo & yahoo. I recently had a lot of previous
"versions" of the Runtime Environment program and a
Microsoft MVP encouraged me to uninstall ALL of them.
After I did that and deleted all "left-over" java-based
files & folders and used a registry cleaner to remove
entries there, I went to
www.java.com ( not Eddy's link )
and got their latest. Have you tried a similar "process" ?
I assume you know to turn OFF any popup blocker
before entering any game room on either site !?
