Need some help help with a new install. Customers are running FMP16 32 bit on Windows 7 Pro SP1 with 4gb memory. When entering an order, about every time they enter the product number and hit tab/enter/return (all are set to advance to next field). Then it gets "Stuck" the item doesn't seem to get looked up. If you click on the background and hit the keypad enter it gets unstuck. Only happening occasionally but more frequently now. Why is this happening? Too little memory maybe? FMP is set at 1024MB cache. My Mac works fine and windows 10 is fine. Not all Pcs have the problem.
