Digital Photo Professional 4 Latest Version - Adjust Specific Area "Undo" Not Working

[SignifDigits]

Is anyone else having this trouble?  "Revert to Shot Settings" isn't working either.  Version 4.21.30.0 on Windows 11 with all Windows updates up to date and operating off of local SSD.

It's annoying, and my workaround is to to a save on all files (easiest way to be sure is to navigate to a new folder "Yes to All" and then back) then go into the file to only specifically perform that function.  Then, if I don't like the results I can just "No to All".

Just wondering if it is me or the software and others are experiencing the same issue.  If the latter seems a call to Canon support to ensure it gets logged as a bug in the workflow is in order.

Seems it is working in Windows 11 Pro but not my Windows 11 Home (I should have been more specific in my OP), and I'm guessing Rodger may be on Home as well.  Thanks for checking and helping narrow it down Newton.

Hello, SignifDigits!

My wife has Win 11 Home on her HP laptop, so I just updated her OS and DPP to current and DPP works fine, so I doubt it's an OS issue. The primary difference in Home and Pro are networking features, but there are a few things under the hood that differentiate the two but I can't see them effecting DPP... But hey! It's been a while since I've needed to know such things 🙂

As Rodger mentioned, it could be a driver issue. But that would depend on your hardware and software configuration. Admittedly, our systems are conservatively set up with primarily graphics programs. My Win Pro systems are all 17"  laptops built as "desktop replacements", so they work well for graphics.

I've been using DPP for a long time, along with other raster and vector graphics programs. In all of those years DPP has had issues just 3 times. One was the reason I joined this forum in 2014, which turned out to be a conflict with a file sharing program I was using (caused DPP to repeatedly hang for 3 or 4 seconds while it uploaded images). Uninstalling the app resolved the issue. I resolved the other 2 by uninstalling DPP, running the free version of CCleaner to clear my registry, then reinstalling DPP. If your issues are troublesome enough, I would suggest that you give that a try.

Thanks Newton.  I actually came to the site because of DPP issue that was a configuration issue on my end, so we have that in common.  I have CCleaner and will give it a whirl sometime soon.  For now I'll just use the workaround and assume when it annoys me enough I will take time to address it.  Thanks!

Even though MS says it’s not necessary, CCleaner registry cleaner was always successful in resolving issues I had when I was using a Windows machine.

My DPP 4.21.30.0 specific area undo is now working as it should.  But proceed with caution.

I have a pair of Nvidia Ada 4000 series 20 GB workstations graphics cards in my HP Z8 G5 and I noticed after an update earlier this summer that when waking up from sleep, it would briefly flash both monitor displays on and off twice.  Not a big deal but annoying and I decided to give Nvidia's latest high performance driver update a try instead of the usual "high stability" driver I use by default.

This cured both the flashing and the DPP failing to respond to the revert command.  The driver software/firmware for workstation cards likely differs from regular gaming/video cards but it might be worth trying a different update.  I will see if using the high performance driver has any other glitches with the software I use and if so I will revert back to the older driver.  I believe in Nvidia's world that the newest high performance driver will become part of the "stable" group after a few weeks if it doesn't have any issues.

Unfortunately, but not surprisingly, no update seems to fix DPP not making significant use of the GPU capabilities. Neither GPU 0 nor GPU 1 (twin cards) show any significant load no matter what I do with DPP and the twin CPUs show only light loading during batch processing of CR3 files but at least the revert button works now 🙂
