I had lately constant freezing of the "Digital Photo Professional 4" running on Windows 10. This would occur after a "Convert and Save" opretation. The windows app goes grey with the message "not responding" in the window title bar.
Having myself software development experience, I used one of Microsoft monitoring tools called "Process Explorer" to monitor the application activity. I noticed multiple attempts to connect to network drives that were in disconected status (see snapshot at the end) - I had many of these drives.
Disconnecting all the network mapped drives solved the issue. It seems that there is some kind of bug invloved when network drives are not connected. I hope that Canon developers check this out.

Thanks for sharing your observations about DPP. We appreciate that!
We can pass this along to our developers, but before we do that I'd like to get some additional details:
We look forward to your reply.

Just a quick update.
I've added again two network mapped disks. I then put these in disconnected state one by one, and tested with DPP4 "CONVERT AND SAVE" using one image.
With one disconnected mapped network drive, DPP4 worked well but I could notice a slight delay during which if a clicked anywhere on DPP4 window the "not responding message" would appear in the title bar and then disapear.
With two disconnected mapped network drives (see attached snapshot), the delay is more evident, the "not repondig message" appears more frequently. In some cases (~1 out 4 saves) DPP4 is not responsive, and I need to restart it.
Note, at the time of my initial message I had 5 mapped network drives in disconnected state. I suspect the more you have of these, the more DPP4 becomes unreponsive in the case of a "CONVERT AND SAVE".
I hope the above helps Canon Development Team to reproduce the issue.
