I have done the update for SetPoint 4.72 without any problem but the problem started after the update. After updating Zomm keys on the Wave keyboard are not working. I have also used SetPoint 4.40 but they do not work with that also. But if you use the SetPoint 4.70 the keys works without any problem. Hence I am using SetPoint 4.70 so that I can utilize the Zoom Keys. But I want to why the zoom keys are not working with SetPoint 4.72.
