Problem solved - a recent Windows 10 update seems to have set “Scroll inactive windows when I hover over them” to on - turning it off removed the issue. Sorry for the false alarm.

Question about using Denoise as external editor in Capture One.
If I choose Open with… on a raw file, meaning that the file is handed over to the external editor without any Capture one adjustments, the file is opened and displayed fine in Denoise, but when applying the changes, it does the processing, does not save the file anywhere.
I also checked and the behavior is the same when just right clicking a raw file in windows explorer > Open with… choosing Topaz Denoise AI. Clicking Apply in the program seems to do the processing but does not actually create a file.
This is the same behavior with Topaz Sharpen AI as well.
However, the older apps like Topaz Adjust AI do ask for a filename to save (as of course it is not possible to resave a RAW file). Can this be addressed?
Using open with opens DeNoise in “plugin” mode so you must use edit with as C1 will pass a file of your choice to be processed.
Plugin mode updates the passed image but is smart enough to ignore RAW images. But, if you pass a dng from a camera that writes dng it will overwrite.

OK, but why are the earlier Topaz programs (Adjust AI) able to ask to save a file - using the same workflow?
Also the issue is not limited to Capture One - it behaves the same when opening a raw file with right click from Windows explorer. The file opens, seems to be able to process fine (progress bar moves etc.), then closes without creating an output file.
It only works if I open the file from within the Denoise AI open file dialog.

Ehm sorry, but that is just bullshit. Why should anyone want a watermark in the images processed with his full price paid product mentioning that it was used offline?! 
If you login once it should keep your login info even if you are offline every other time.
Oh okay! This should be mentioned in the changelog as well. 
I added a note to it to hopefully clear it up.
Adam, the new previews of all modes are terrible. Look what happens to edges. Turning down the “Enhance Sharpness” slider to the lowest possible did not help. Seems to be only in the previews, not in the final saved results.

I’m having the same problem after upgrading to v3.0. Besides that, the sharpness enhancement doesn’t seem to be as good as before.

Since I upgraded, DeNoise no longer works with my graphics card (NVIDIA GeForce RTX 2060 SUPER). How do I roll back to the previous version. I can’t find the old version on the Topaz website, is there a link I have’nt found??

Is this for all images? What type of hardware/OS are you on?
You can get links to previous releases in their respective threads: DeNoise AI 2.4.2
You can also take the link for a version and change it to any other version and it should be a valid link.
I’d also recommend trying to update your drivers first to see if your issues are resolved.

I am running Windows 10 in 64 bit with an NVIDIA GeForce RTX 2070 super and the driver version 461.72 DCH. Yes, it happens to all images.

Same issue as Imo here on NVIDIA GeForce RTX 2060, Windows 10 20H2. DeNoise AI always fails, but AI Clear works OK.
Time to drop back to 2.4.2.

check your GPU driver.
I pulled a few images off of r/OldSchoolCool to test on this new version and something isn’t right… all of the models make the images look extra pixelated. Hot garbage:

Edit: I tried the first with CPU and the second with GPU.
We’re looking into a few cases of this currently, so hopefully can resolve this in a future patch. Do the older models/engine work well on those images for you?
