I know that.   Hence the answer from  Precious B above- makes no sense.

I can not make a specific account inactive, because even though the register shows 0

if you try to make it inactive  you get the response:
This account cannot be inactivated because there are transactions in it that have a non-zero balance.

so.....   that sucks.    The account in question, in the desktop version, WAS inactive. WHen I did the conversion yesterday, it is now showing up in the CoA...
