Freeze Panes in Shared Workbook
 

I'm having an issue with a Shared workbook losing the pane freeze
sporadically. 3 users typically have the file open (set to track changes and
update every 5 minutes.) It can lose the freeze for one user and the freeze
would still be viewable by the others. Lets assume operator error has been
ruled out. Is this just a bug or is there a way to prevent this from
happening.
