SalesPRO does not respond in the expected
manner after an external monitor has been disconnected. This may happen
because a certain window, such as Edit Product Item, is displayed off
the main screen, on a monitor that no longer exists.
This
issue will manifest in various ways, depending on which items were last
displayed on the external monitor. You may click on Add Product in
order entry and nothing happens. Or you may open an existing
Quote/Sale/Order and not be able to see it.
