I need a live slider on a window. I used the Button Demo example in the FBtoC folder and added a slider in IB with the Live option selected. I added a command id and was successful in setting the HiView field in the example with a value based on the slider position. While the field updates when the mouse is released, I can't get the slider to act as a live button and update the field while the mouse is down. Adding a beep shows the event is handled when the mouse is released. Does this mean a different kind of command handler needs to be used? Or is there a setting for the window to get live events? Or do I need to create a loop while the button is down? Thanks David
