At my company most users have Internet Explorer 6 or 7 and Java 1.5.06 installed.
From time to time a user will report that an applet is not functioning. I note that the Extras-->Open Java Console menu is missing in the browser. The Java settings app in the Control Panel is still functioning and indicates that IE is enabled for applets.
The only solution so far has been to reinstall Java. It then reappears in the browser and the applet works.
Has anyone had a similar problen or have any ideas what the cause might be?
