Problem solved!
![smile :)](http://pixinsight.com/forum/Smileys/default/smile.gif)
I originally tried to load approximately 100 RAW CR2 files into
Blink and that is when the very slow operation problem occurred.
I retried today, but loaded only about 40 files into Blink and everything worked OK. It takes my machine about 4.5 sec to load each of the original files, so, it took about 3 min to load the 40 files. It then takes about another 1.5 sec/file when I click the Histogram button (thus, clicking the Histogram button required about 60 sec to perform the auto Histogram on the 40 files). At that point, using the Right/Left arrow keys to move to the Next/Previous image is almost instantaneous.
Apparently 100 images is just too many for my machine to handle all at once, but 40 was OK. I didn't investigate further to see how many I could handle before my machine "choked up".
Hopefully this information will be helpful to someone else.
