Fred (developer)sighle (owner)1. both of us have the course open2. fred checked out at title level3. added a page at the bottom of the course4. tried to check in the course, got the check in box, clicked ok and got an error:"Checkin failed. Title out of sync. Please refresh the Title before proceeding."5. When Fred clicked OK, it closed out all the windows and still showed as "checked out" to sighle6. fred re-opened the course and tried to check in changes and couldn't --- he could select "Undo Check Out" with no problem.
