Welcome to Seven Forums amir57. It looks like you had a folder/directory hang up while opening, and when windows asked if you want to troubleshoot or close, you chose to close. Does this sound familiar? If it was an isolated problem, I'd not be concerned. But if you are having recurring problems, we'll try to dig into it a bit more. A Guy
