That was it!!! Thank you soooo much!!!! I don't know how I did that, but now that I know what it does, it could be helpful in certain situations.

The selection tool only works in some situations, though. It's still a problem that it's filling in more than the square I've drawn out. In some squares, I have another object in them and it's even filling in that object too and no selection tool can account for that. Doesn't anyone know what setting I can change to make it start working the way it has for the past two years? I'm so frustrated. I was in the middle of working on something and I can't do anything else with it until I get this resolved.

I just figured something out. When I click on an area with the paint bucket, it changes every single area that is the same color. So, that has to mean something, right?

Even with the tolerance at 0%, it still does it. The rectangle select works for now, thank you. But I'd really like to figure out what I did to get this setting this way so I can change it back.

I have been working with Paint.net for a couple of years and have never had this issue before. Suddenly, today, I tried using paint bucket to fill in a square and it filled in the entire image. I don't know if I accidently changed some setting on accident or what. Does anyone have any idea how to make this stop so that the paint bucket only fills in the area I have outlined for it?
