I do online karaoke. I am trying to use my webcam to do this and everytime I start to use it my internet explorer crashes saying the file that caused the error is quartz.dll. Does anyone know how I can fix this problem? I am using a creative webcam NX and have downloaded all drivers including the new ones directly from creative’s sight. I have also done all necessary windows updates as well. I am perplexed as what the problem can be?
