[GNC] Unable to Hide an Account

[Tom Route36]

For the most part I can hide and unhide accounts in GnuCash without any 
problem.  But today I ran into an issue where there's one particular 
account of mine that seems to be permanently unhidden. In the Edit 
Account options window for that account I can check and uncheck the 
Hidden checkbox just fine.  But for this one particular account GnuCash 
seems to ignore the Hidden setting.  This one account stays persistently 
unhidden regardless of the Hidden checkbox setting.

Has anyone else run into a situation like this?  Any idea how to fix the 
problem?  Note: I do NOT want to try deleting this account.
