Focus Problem When Taking Digital Camera Pictures

[Henry The Octopus]

Occasionally when taking photos with my digital camera, particularly in flight, the camera focusses on the windscreen rather than the object I am trying to photograph. Other than a clean windscreen (which doesn't always solve the problem) can anyone suggest a way around this please. There is no manual focus option that I can find.

My camera is a Kodak DX6340. Otherwise I am very happy with it.

Thanks in anticipation.
