Not a huge deal but noticed today that if I drag and drop a color onto my workspace it doesn't work. I have to drag it off the workspace in order to get it to work. It is like my mouse is several inches off from where it should be when dragging and dropping colors. Normal dragging and dropping works just fine so far on everything else. This started happening after upgrading to monitors that have a 3840x2160 resolution. Anyone else notice any glitches like this when running extremely high resolution monitors?
