When Mutliple JRE 's installed on the system and if an applet is run specifying the particular version of Plug-in (Unique CLSID and MIME type) the collision detection message dialog is not shown but shows "Fatal Error" message.

When an applet is running in a browser with Plug-in version 1.3.1 (1.3.1 CLSID and 1.3.1 MIME type) and tried to run another applet with Plug-in 1.4.0(1.4.0 CLS ID and MIME type) in the same session of the browser , the collision detection message dialog from Plug-in doesnot popup to warn the user about the collision saying another version of VM is already running attached to the browser process.

To reproduce the problem :

1. Install ladybird (JRE 1.3.1.)
2. Install Merlin build 90/91
3. Bring up the browser and load the following applet

4. Verify that the applet is running using Plug-in 1.3.1
5. Load the following applet into the same browser session in which 1.3.1 applet is already running.

6. You will notice "Fatal Error" message , Plug-in should pop up waring collision detection message instead with appropriate message to user.
