The screen shot below shows 13 images all open similtaneously each in its own window. Hidden behind them is the main DPP window in which the folder contents are displayed as thumbnails in the main browser pane. There is a single Tool Pallette open, it is active for whichever open image window is selected and edits can be made to none or all of the open images. Note that the DPP mode "EDIT IMAGE" has NOT been engaged. Note also that in the hidden DPP main browser window all the thumbnails are shown, this is called THUMBNAIL display, this is chosen in the control section along the bottom of the main window on the left hand side. Also note that neither of the other two display modes MULTI_LAYOUT VERTICAL and HORIZONTAL modes have been chosen, these choices are made on the bottom control strip and are adjacent to "THUMBNAIL"
If either of these two display modes "MULTI_LAYOUT" is selected the image viewer changes modes and will display only a single image window, period. I believe that in both of these modes only a single image window will open. In the situation that there are multiple image windows open then selecting on the lower left the choice MULTI-LAYOUT immediately closes all the images but one.
This is what I encountered when I originally used DPP4 for the first time. I probably chose the vertical multi-layout display without thinking much about it, not realising I put the system into a mode that prevents opening more than a single image. Perhaps Canon has a good reason for making DPP4 work this way I don't know.
There is more.
In the Main window is a menu TOOLS. There is a choice PREVIEW SCREEN DISPLAY SETTINGS, the default following installation and power up is the lower of the two choices PREVIEW. The other choice is MULTI-FUNCTION PREVIEW. Starting in normal preview screen display mode "PREVIEW" when there are multiple image windows open, if the choice is changed to MULTI-FUNCTION PREVIEW then all image windows are closed except for one. It is not clear to me at this stage the reason for this choice, I am sure Canon has a good reason for this.
The DPP4 user instructions make reference to this TOOL menu choice of display setting on page 34.
The issue of how DPP4 behaves when the EDIT IMAGE main window choice is made has not been investigated, I am worn out from investigating preview displays.
So it seems the answer to my original problem is that the system is designed to work this way, there are some fundamental system operating mode choices that follow from user input commands and the consequences of which are profound. In my opinion this subject deserves a very high priority in the user instructions, where at present they are not discussed at all, I believe I shall offer this suggestion together with my unsatisfactory experience to Canon Inc.
I also feel badly let down by the Canon Inc expert Tim whose advice early in this thread to CHOSE the multi-layout main view does in fact induce the "single image" problem even if it didn't exist beforehand.
As I said in the beginning I am a beginner with DPP4. There may be things I am overlooking.
Good sleuthing! I guess the reason I couldn't reproduce your problem is that I'd never used (or even noticed the existence of) the "Multifunction Preview" option. If you do manage to get Canon's attention, I'd be interested to know why it's called that and what it's for.
You might also ask them to explain the striking difference in functionality between the "Save" tab on the main window and the "Save" command in the "File" menu.

Thank you.
Using the new install the behavior is exactly the same as before, double-clicking the next image "usurps" the window already open for the first, one image window only is permitted. This is not how DPP is expected to work and I am baffled.
This is how the screen looks
I appreciate your help so far, any further suggestions are welcome.

I don't know what to tell you. It doesn't do that to me. Is it possible that you're short of memory?
Have you talked to Canon Support?
