In QR-History Service, in the QR-History dialog window, there are Open, Start/Stop and Apply buttons. What are they individually for?
1) When I want to "History downloading for selected period of time", after I set the from and till dates, I don't know which button should I click. Sometime the Open button nothing happen. Then if I click too many buttons, the dialog appear to freeze and return after I leave it alone.
2) Which button should I click if I want to "Request history" Text(ASCII)? Apply?
Thanks.
