I've testing out SC3 after user the former version for years. There seems to be some type of disconnect between the "Calculate Similarity" window and the "Preview Article" window.
I spun 6 articles and clicked the button to see how close the articles match. I then modified the articles in the "Calculate Similarity" window and then clicked the button at the bottom to "save changes to Preview Article Window." It looks like the article were being updated correctly in that window after clicking the button. However, when I closed out the "calculate similarity" window ALL of those articles in the "preview article" window reverted back to the original article. This is quite odd. Is there any reason why it does this?
