Posting to inactive Sales Account

I am having problems with Vantage allowing the posting of an A/R
invoice to an inactive GL account. We consolidated product lines and
I inactivate the GL account for sales but it still allows the user
(who obviously is not checking their work by reviewing the edit list
before posting) to post to the inactive GL account. Anyone else
having this problem?

We are using 8.00.812
