This issue seems to be specific to my OS(Win 10).On my previous laptop everything worked fine.Here the menu with the file with the 'file,render etc' options isn't available isn't visible. And the window is as fully maximized as it could be. In the screenshot my mouse cursor isn't visible either. Also the text, menu and stuff in the lowest portion isn't fully visible. Kindly help. Thanks.
