Please help a Mac newbie. Im having bad luck installing and using a Logitech Quickcam Pro 4000 on my Mac Mini under Leopard 10.5.1. I went to VersionTracker.com and downloaded Logitech QuickCam.dmg vers. 8.0.1. I ran the .dmg file and it installed QuickCapture.app/ I plugged in the camera and ran QuickCapture.app. The application found the camera and I was able to change the screen size from 320x240 to 640x480. After a couple of minutes the QuickCam screen loses its picture and the window turns blue; a pop-up window says, An unexpected problem has occurred. (gpc:706). Sometimes I get a spinning beach ball and have to do an opt-cmd-Esc to quit the application. I erased the .dmg and .app files; did an new download and install. Got the same results. Id sure appreciate any help, ideas, etc. that you may have. Thanks, -Nick T.
