How can I stop QuickBooks from creating Renaming Rules? (I'm updating my checks from Online Banking and everytime I assign a check to a payee, QuickBooks tries to make all the checks to that one payee)
You can't. This feature of QB 2009 is quite broken, and there really is no solution at this time. I encourage you to join the Quickbooks Inner Circle. In my estimation, this is the only forum to which Intuit seems to pay attention. You can join it here: http://quickbooks.satmetrix.com/quickbooks_innercircle/index.jsp...
You will find that this issue has been raised in the Idea Exchange of the Inner Circle. Please make your opinions known there, if you have not already.
