I was having network issues with Creator so I rolled back. still no problems with 1607. I decided to clean install on a spare disk. All loaded except I can't seen any program windows. When I open a program it appears on the taskbar but I can't open its window. The display areo appears to be showing me that it is on display 1. It looks like it installed the nvidia driver in the install process. I do not have 2 displays but it is acting like it is displaying the window on another display.
