Kirk:
You pointed me in the right direction but the problem was not the default ICC profile. I changed it from what was there to "Adobe RGB (1998)" and hit the "Apply" button but nothing changed. Doing that did not get rid of the overall color cast (it actually is not sepia, that was just the closest that I could come to describing it). However, when I unchecked the two top box ("Color manage thumbnails for display") and then I applied that, that got rid of the color cast. Do you know what is going on and, more importantly, where else that problem might show up in my workflow? I can't risk having that happen when I send someone my photos or put them up for sale on Digital Railroad. If we cannot figure out what is going on, I will have to use a different program (like ACDSee), even though it may not have some of the features that I want.
