Hi Derek, Wayne,
looks like a bug in Orthogonal Views; it should not throw an exception
but rather complain about the cause of the problem or avoid it.
It might be caused by an invalid 'voxel depth', i.e. by a wrong
calibration of the depth scale (spacing between the slices).
Please have a look at Image>Properties, to check the voxel depth.
It this value is ok, do you have a hyperstack? (more than 3 dimensions)?

@wayne: I would suggest the following modifications in Orthogonal_Views:
line 235:
int height2 = Math.max(int)Math.round(fp1.getHeight()*az), 1);
line 256:
height2 = Math.max((int)Math.round(fp2.getHeight()*az), 1);
These should avoid that an image with width or height of zero is created
even if the spacing between the slices is so small that the depth of the
stack would be less than one pixel at the x and y scale.
Michael
