From the above forum thread, some developers need to be able to switch between old and new java plugin via the Java Control Panel running as standard users.
The problem is due to currently the info. regarding using new java plugin is being stored in the HKLM branch of the registry which requires admin. privilege in order to modify it. We may need to store the same info. in the HKCU branch.
Not only can non-admin users switch between the new and the old java plugin on Windows XP, but it also seems that the administrator can't change the settings for regular users.
The plugin setting by an administrator does not affect browser's behavior in a standard users's environment. This is then compounded by the fact that a standard user cannot configure his/her own plugin setting on Windows XP.
We have a situation where regular users on Windows XP are not able to use the classic plugin because there is no way to disable/change their settings to do so. They always end up using the Next Gen Plugin - which is not acceptable in this customer's situation.
