Anyone got exception running VW GeometricsObjects Examples?

Hi,

[VWNC 7.4.1 on Windows XP]
It's strange that they run smoothly in an original image but while have some
packages loaded Geometrics Examples will cause exception and VW halt there with
shift+ctrl+y getting no response. And the exception window is not rendered well
before system die.

I don't know what causes this. Maybe the Unicode support?
Anyone who have ever got this kind of exceptions, please?

Best Regards,
Jim G
