Occasionally I get a complaint from users that the "system froze" for a short time - then was fine. Recently had instance where a very simple 'update' that usually take <1ms took 4 minutes - can anyone suggest why this would happen.
The "zsys" table has just one record and tracks various system parameters - in this instance was providing the next QuickQuoteNumber then being incremented by 1.
