I have exactly the same problem when trying to run Editor it loads a up to 100 percent and go to statusbar, in task manager process is running. When trying to click the status bar icon , nothing happens , if i try to switch with alt + tab , nothing happens. I have a feeling that the editor is working , but just can not be displayed.
I have latest Nvidia drivers. System was installed few days ago. I ran verification, i installed version 4.6 and all time i have same problem, initialization to 100% and disappears.
But i have log.link text
