I blanked out our #1 checking account in AD-B because we no longer have that account and my AR staff seems to always pick it.  While I was in AD-B, I noticed that AR, AP were both set with a default account of #1, so I also changed those to #6 which is our current checking account.  AR seems to be working fine, but AP-R seems wacky.  In AR #6 is still our current bank, but in AP#6 is now #5.  To make things more complicated, we had a check run today and we posted AR payments, so I can't just put it back, can I?
