I have created a large Window in OPTO22's Factory Floor v4 OPTODISPLAY. It is a list of parameters with 4 columns beside them showing setpoint, actual, min and max values. I want to be able to scroll down to the bottom of the page to view the hidden text. I have tried the 'slider'option under the operator driven attributes but this didn't work, it only operated in the visible portion of the window. Can anyone tell me how to do this.
