Does anyone here frequent the great free web page on FlightExplorer.com that has the TerraExplorer 3D view of flight tracking?

I have tried to use it many times and really enjoy it but it locks up both my computer at home and at work whenever I use the 3Dvideo from Terra Explorer that is offerred.

I think it is a Java problem but I have the lates files. Can someone offer advice if they have had this lockup problem that requires a reboot?
