This problem is with your Java Virtual Machine (VM), software that runs java programs such as MERLIN Online.
If you're using Netscape, make sure you're using version 4.08 (or Communicator 4.6). Note that newer Netscape and Mozilla browsers do not support the Microsoft VM and will not work correctly with MERLIN Online.
The Microsoft VM is recommended for MERLIN Online. Sun also offers a Java VM but it causes inconsistent errors in MERLIN. To test which VM you are using visit: http://www.java.com/en/download/installed.jsp. You'll want the vendor to be listed as Microsoft.
Microsoft no longer distributes new installations of their VM because of legal issues. You can still download the Microsoft VM from independent Java developers. To find one of these, visit a search engine and search for microsoft virtual machine download. Note that any search results from microsoft.com will lead you to the wrong VM, so ignore those results. Visit one of the resulting pages, download the Microsoft VM, then follow these steps to install it.
1. Optional Step: Use Add/Remove Programs (in Control Panel) to uninstall the Sun VM. it will most likely be listed as "Java Plug-in..." or something that mentions "Java". Performing this step will result in the Microsoft VM being used any time you visit a website that requires Java. You can optionally leave the Sun VM installed, as described at the bottom of the page.
2. Run the file you downloaded to install the Microsoft VM. Restart the computer if prompted.
3. If step 2 results in an error message similar to "this is for updates only", repeat the search for the Microsoft VM and download from a different location. Repeat step 2 with the newly-downloaded file.
4. Visit windowsupdate.microsoft.com and install any critical updates.
The Microsoft VM should now be installed and ready for use.
If you want to leave the Sun VM on your computer, you can skip step 1. Just make sure to set the Microsoft VM as the default Java application before viewing MERLIN Online. You can change the setting for the default VM in the Control Panel applet for the Java Plug-in after installing the Microsoft VM, or under Internet Options - Advanced in Internet Explorer.
