(2) is not the case. lol (1) might be the issue. There should be an OK button at bottom of each option window. You can drag the option window up from the very top, see if you can drag it up enough to see the OK & Cancel buttons.

Other than this, perhaps reset resolution either via right-clicking the program, else in main settings. Perhaps try the first option first in the Compatibility mode option after choosing Properties. ie: right-click LW shortcut, choose Properties, choose Compatibility Mode tab, see options below it.
