We've had a couple of reports of a problem running the IDV under the latest 10.4.3 release on systems with NVidia 6800 graphics cards. Apparently, the latest update includes some OpenGL driver updates which we think may be causing the problems. The problem is a persistent flashing on the screen (even after the machine is rebooted). If you are running 10.4.3, we suggest you don't run the IDV until we come up with a solution or workaround. Thanks to the IDV community of users for finding this and helping us solve the problem.
