OS tested - Win XP Home
build tested - j2sdk1.5.0-b37

Steps to Reproduce -

1) Install j2sdk1.5.0 on the local machine from -
/net/koori.sfbay/p/jdk04/jdk/1.5.0/beta2/b37/bundles/windows-i586

2) Check that Plugin is enabled for Intenet Explorer in the Control Panel

Advanced -> <APPLET> Handling
Internet Explorer should be checked.

3) Open IE browser, and make sure you can launch Plugin by launching any of the plugin demos.

4) Also, in the browser, go to
Tools -> Internet options -> Advanced
And make sure that Sun Java is present.

5) Close the browser, and disable Plugin for IE in the Control Panel.

6) Open the browser, and again check under
 Tools -> Internet options -> Advanced
Sun Java will not be there.

7) Now try to launch any of the 1.5.0 specific demos, and the Java Plugin Warning window comes up saying

"The applet(s) in this html page requires a different version of java different than the one the browser is currently using. In order to run the applet(s) in this html page, a new browser session is required"

If "Yes" is pressed, the same message comes up again.
If "No" is pressed, then the following message comes up

"Sun Java is not currently selected as the default Java for this browser. The Sun Java Console option is only available when Sun java is the default java for the browser. To select Sun Java, go to
Tools -> Internet Options.... and select the Advanced tab"

The above message is misleading to the user as Plugin can not be enabled in IE as mentioned in the displayed message.

The user can enable Plugin in IE through the Java Control Panel. And the message displayed to the user should give the right information.
