AR Invoice History Inquiry Launched from Customer Maintenance Slow

SOLVED

Using 2019 Premium Product Update 2.  Can't seem to find a pattern, but sometimes when drilling down to a historical invoice from Customer Maintenance, it takes a considerable amount of time for the historical invoice to appear.  I've replicated the issue on both client workstations and Sage application server.  Just curious if anyone else has experienced and/or found a resolution to it?  (KB article 38605, which I believe references the same issue, can only offer 'Pause before opening another invoice' as a resolution, but that doesn't seem to work 100% either)
