If you were interested in pursuing this further, there is a 'System Updater' that is available for download and installation. It is a recent fix to just the common system files such as ADS32.DLL and others to address an issue with exporting information to Excel.

The version of ADS32.DLL installed is 1.12.54.2609, which is even more recent than the one installed by the Receivables hot fix. If you were to install this system file update and the Payables problem re-occured, that would absolve the Receivables program updates as the reason and point more focus to the common system files.
