Yes, please send the show file with the problem our way. I also cannot reproduce this on any of the show files we have here on file but if you got one causing problems we can definitely see what's going on.
Can you please create a backup of the showfile and send that to me? Setup - Shows - Backup What you sent was a zipped file of an un-archived show file.
This is a toxic combination of Programming Preferences -> "Close on Clear" checked AND "Follow Current" selected. Happens with any show file. Michael logged D-2652. You can uncheck Close on Clear as a workaround
