Thanks for the pointer about the plugin. I've found that uninstalling and then reinstalling JDK1.2 also seems to help. -Christopher -------- I had a heck of a time getting my Netscape 4.5 browser to run any 1.2 applets (I am running Windows NT 4.0 SP3). The problem I had involved incorrect registry settings for the current user (profile) in Netscape. The solution to the problem is described at the following web site: http://java.sun.com/products/plugin/1.2/plugin.faq.html#trouble However, I was unable to get the registery settings correct by adding another user using the user manager as this document suggests. The only way I was able to get this to work was to manually add the registry settings to their correct values. Perhaps this may help others trying to view the 1.2 DIVA applets. - Mike Wirthlin -- Michael J.
