I was provided with an answer however when I followed the answer it did not solve my problem. If I have a text file scrolling and I select a different text file to scroll, instead of replacing the previous text file the app appends the second text file and after a while I find it is scrolling all text files I have been texting with. I cannot delete the file name in the setup window, I can only select a different file. The app does not replace the original text file it appends the new text file. I have uninstalled the program and reinstalled it but the program behaves the same. I am running windows 8.1. Is this a factor?
