I am having a few problems with my install on my windows 8.1 It keeps asking if I will give it permission to make changes and when I say yes MC 20 blinks and becomes MC 19. So I want to delete MC 19, but when I try to use uninstall it through the Control Panel the MC message window that I need to check to give it my OK is so large I can only see the top part of the message and cannot get down to where I need to click it to uninstall. I tried changing MC fonts - I tried changing screen reolution - so far nothing will make this pop up small enough for me to use. Size is fine on Vista machine.
