Detailed clouds disappear

Whenever I create a flight with real weather a grey, foggy sky appears and not the detailed clouds and blue skies. The weird thing is that when I open a Top Down window the detailed clouds appear!! Closing the window again makes them disappear. Has anyone ever experienced something like this? Can anyone help me solve the problem?
