If I apply an ROI to an image and display it, the results are fine IF
I set the valid region to that outside the ROI, i.e.
  roi = ilRectRoiCreate(100,100,150,30,512,512,0);

However, if I set the valid region to be within the ROI
  roi = ilRectRoiCreate(100,100,150,30,512,512,1);
The top half of the image is garbage, although the bottom half
is OK.
The image is a 512x512 TIF file.

Any pointers here would be greatly appreciated.
