Trouble shooting:

If you don't see auscomp's logo on the top - the following could be the cause:

The JAVABundle.zip did not extract properly.

When you extract the zip file into the directory of your choice, there should be three sub-directories created - JTab, JTabTree and JTree. If you are using WinZip, make sure that the check box "Use Folder Names" is marked because of these three sub-directories.
