OT: unregistered OpenCube DHTML Effect

[Chris A Czerwinski]

I know this is Off-Topic but ...

When I visit a site and I get the following error dialog message

-----------------------------------------------------------------
[JavaScript Application]

! Error-Unregistered OpenCube DHTML Effect - (www.opencube.com)

-----------------------------------------------------------------

afterwhich I can't use their Drop-Down Selections from their Tabs

What does this mean?
 Is it their WEB Site that hasn't registered their Java Utility OpenCube?  
or
 Is it my Mozilla 1.4.2 that needs a OpenCube plugin?

I have j2sdk1.4.2 installed on my system with Mozilla Plugin 

 libjavaplugin_oji.so ->
   /usr/java/j2sdk1.4.2_03/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so


Web Site that I'm encountering this error is http://www.mastech.com/

Any advice?


Thanks
