OK, here's how it is done.

Put the image into the Editor.
Crop the right side out, leaving the blurry left side alive, BUT, watch the pixel count as you crop.
By that, I mean suppose the image is 3266 pixels wide. You crop the right side out leaving 2266 pixels inside the crop. Now, FILE SAVE AS...
Now crop the left side out and make the right side 1000 pixels exactly... (Orig was 3266. We cropped off 2266. Balance is 1000)
SAVE AS

Now put the saved Left side into the Editor and sharpen....
Now put the Saved Right side into the editor and sharpen a little or whatever might be needed.
DONE!!
Now clear the queue, and place LEFT SIDE into the queue at a size that easily fits both parts side by side on the same page.
DRAG the Right Side image onto the preview panel to the right side of the first one.
Open the Page editor. See the two images.
Use CTRL and ARROW keys to butt them together.   

That's it!!

Have fun!
