Why would using a Qualifier create a bounding box?

Another glitch I've encountered and cannot figure out how to get rid of it.

When I now attempt to set up a color Qualifier, my eyedropper doesn't select the desired color. Nothing happens. Only if click and hold then drag, will there be a dashed bounding box. But even then, no colors are being populated in the Qualifier panel. For the moment, I just have to use the HSL sliders to create my qualifier.

ALSO, just now finding out, that I cannot adjust any of the points from a Power Window. If I click and drag a point, nothing happens to the shape AND the dreaded bounding box happens again.

Has anyone else had this issue? I don't have any new Windows apps that I can think of that might interfere. Please advise.

You're using a standard 3 button mouse?

I have seen the Qualifier occasionally "choke" and get confused and be reluctant to grab the right color. Just as a test, take a piece of SMPTE color bars from the generator on the Edit page, make it a compound clip, then come back to the Color Page. See if you can select and isolate each color in the Color bars.

If that works, then I'd question the color space of the specific clip you're trying to qualify. Is it possible it's not in the right color/gamma space? Is it being color managed in any way? Is this a Log space clip or a color-corrected clip? In general, I try not to do an qualifying until I'm at least 10 nodes away from the initial color corrections, and once I do that I never touch the overall color until it's a trim node way after the qualifier. The Order of Node Operations is still very important.

In cases where I suspect the node just got corrupted, I'll delete the node, create a new node, make it the new Qualifying node, and try the qualification process again. Make sure the Key inversion button isn't on. Worst case, try the 3D keyer and see if you get better results.

I'm not sure what this has to do with the actual functioning of the qualifier. The issue I've encountered is that if I were to click on any part of the image, nothing is selected. Nothing happens. Not even a 'wrong' color. The qualifier panel doesn't change in anyway to indicate that some color value was selected. That being said, I did as you mentioned above, and I get nothing; unless I click and drag, however I get a bounding box instead a range of selected colors for the qualifier panel.

Yes. However, I've been using a 3 button mouse since Davinci 12.5-ish with no problem.

OK.

When you say Display Scaling are you referring to the Windows system. In my case, everything is at its native full resolution. If in Davinci, even though I'm using 4k footage, my timeline format is half that size, just to be a bit faster.

Yes.

There is no Disabled. There is Full, Half and Quarter.

Keep it at Full.

I had this exact issue. Brutal. On Mac. Restarted resolve and issue went away.
