Take a look in the Startup items and see if iListen is starting up when you boot. If it is, take a look at the iListen preferences to see if there is anything that would change the color settings on your monitor.
Try uninstalling MacSpeech iListen and see if your color comes back.
I've just installed MacSpeech iListen. It went well, but now my display is in grayscale. The settings say it's trying for millions of colors in the max resolution. Changing the settings for colors and resoultion haven't changed this behavior.
The computer boots normally. The gray splash page looks right. The blue splash page is full color. When the desktop is first shown it is in color until something loads. It might be the iListen stuff or it might be something else.
The System is a 17" PowerBook G4, 1 GB. OS Version = 10.4.8. I've run verifying permissions on the disk.
Does anyone have a good way to deal with this problem? Thanks
