Rod,
How did you try to edit the sequence? The correct way to edit a running sequence is to go into Monitor, go the to Sequence tab and click the Live Edit button. If you do it this way, it should not complain that the sequence is read only.
When you click on the Live Edit mode it will check you really want to do a Live Edit, and if you select OK then it opens up a cut down version of authoring. When you are finished making your changes, click the "Apply Changes" button and it should save the changes and take you back to normal monitoring.
If you just close the window, then next time you do into monitoring it will say something like "Hi <name>, you haven't finished editing <name>. Click continue to proceed." Then if you click continue it will take you into the Live Edit screen to do your changes.
But if you log in as a different user and try to go into monitoring, then it will say "Sorry, <name> is currently being edited by <name>" and you won't be able to do much.
It sounds like you have got into Live Edit mode somehow or you wouldn't get the editing message. Are you going back in as the same user?
