KLJ, you sent me a message "The auto scroll changes to stop, but does not scroll." but this is best kept public in case anyone else has the same problem. There have been no other complaints about the auto-scroll so it is almost certainly a problem on your PC and not with Chordie.
Have you tried jet60's suggestion? Clearing out the cookies can solve a myriad for niggles (I have other good reports about CCleaner, so that might be worth a try).
If this fails then you will have to contact Per, the site owner, who understands the working of Chordie better than anyone. You will have to let him know your operating system (Win Vista, 7, 8 etc) your browser (I.E. 8, 9, Firefox etc) and give him exact details of what is happening ('not working' is not a good enough description to fix any problem on anything). You can contact Per at: admin@chordie.com.
Please keep us posted of developments in this thread.
