Not sure where this question belongs. A friend likes to do the jig saw puzzles at Jigzone.com. Has been doing them for a long time. Suddenly, the puzzles will not "load". We have done all the "fixes" recommended by jigzone to no avail. Java is installed and working as the various tests show that it is. It is the SUN version of Java. We downloaded and installed the latest versions of Mozilla Firefox and Opera but this made no difference. We uninstalled and reinstalled JAVA - no luck. We have checked all the security and java settings. We have removed temp internet files. Any suggestions.
