Java robot class capturing black/blank desktop images - Help

I am currently capturing various images from the desktop using the robot class. Yet every now and again my program will take a completely black image, which renders my program useless. Does anyone have any suggestion why this is happening ? and what I can do prevent or fix it ?

At the moment I just restart my computer and it seems fine, but I don't want this to happen on my clients computer.

Thanks

How are you running the Robot?

     try {
                  Robot robot = new Robot();

                  //capture a screenshot of desktop size
                  Rectangle captureSize = new Rectangle(Toolkit.getDefaultToolkit()
                              .getScreenSize());
                  BufferedImage capture = robot.createScreenCapture(captureSize);

                  //save to file
                  ImageIO.write(capture, "bmp", new File("C:/Desktop.bmp"));

                  //Set Desktop Image
                  desktopImage = capture;

            } catch (HeadlessException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            } catch (AWTException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            }

The screensaver hasn't kicked in has it?

No all screen savers are disabled, it just returns a completely black image. I don't think its my code, do you think it could be a different program interfering ?
