We have recently encountered a problem where a badly written Web Camera driver for Mac OSX causes ProSelect to crash on launch. The driver connects into QuickTime and causes a crash as soon as ProSelect tries to connect to Quicktime. The specific webcam causing the problem is made by Sonix.

If you are experiencing this problem then you will need to uninstall/remove the drivers for this camera and perhaps disconnect the camera itself from your computer. It may be that the problem can be fixed by using updated drivers from the supplier but we have not been able to check this ourselves.

One way to verify that the cause of the crash is caused by the driver is to view the Apple Crash Report that appears when the crash occurs.  Below is the section from a computer with the the webcam installed. You can see the references to  sonix.webcam near the top of the listing:
