ddraw.dll problems

Hi,
I downloaded the new all-in-one Jython/VisAD/Java3D installer. It's a cinch to use. However, when I try to run my Jython scripts using VisAD, they start up OK (so I know they're importing visad, subs.py, and finding Java correctly), but on trying to produce a display I get this message: 

"java.exe - Entry Point Not Found
The procedure entry point DdEntry12 could not be located in the dynamic link library DDRAW.dll."
When I click OK on the dialog, I get the error message appended to the bottom of this message. I'd be really grateful if anyone could suggest potential sources/causes for this message. (FYI, I'm running on Microsoft Windows 2000 [Version 5.00.2195]). 

Thanks,

-Frank
