I can't reproduce this on my system (XP SP3, IE7, Nvidia board).
Need more information about the configuration.
Please run any java app from the console, with this env. variable
set:
J2D_TRACE_LEVEL=4
and provide the output.
Also, please make sure that you have the latest video drivers. If updating
the drivers helped, please let us now the driver version which
helped (can be obtained with the same J2D_TRACE_LEVEL env. variable).
But please save the version of the driver that didnt' work as prior
to updating.

Closing the report as the submitter has confirmed upgrading the video driver has resolved this problem.
Posted Date : 2008-11-24 06:32:16.0
Re-opening to address issues with older device drivers.
Posted Date : 2008-11-26 02:51:11.0
Need to block drivers earlier than 6,14,10,9381 .
Given the number of issues with Quadro FX line with older drivers we should
consider limiting the driver version for whole line.
