Logitech Quickcam Zoom Compatability?


I have installed the camera with the latest software several times (completely uninstalling the previous installation each time)and it only works in black and white, occasionally in colour. I have contacted tech support for Logitech and they tell me it's been tested to OS X 10.4. I am using 10.4.2. Can I downgrade to 10.4.0 so I can use my Camera? OR, is there a setting within Tiger I can adjust to make the cammera work better. I Returned my first camera because Logitech said there might be something wrong with the camera and replaced it with a new one but the same thing still happens.
Thanks Again, Jim
