I collect and catalog pins. After scanning, I use Photoshop Elements to clean up the pin scans, especially the backgrounds. I had been using the lasso tool to define an area that I needed to change the color or make the color uniform. Once the area was defined, I would then fill in the area with the desired color. This procedure no longer works. I get an error message: "No pixels are more than 50% selected. The selection edges will not be visible." Why did my procedure quit working after more than two years of using it? Is there a setting somewhere that somehow got changed? I use an Epson flatbed scanner and have not changed any of the settings when I scan the pins.
