This occurred the first time I ran the program, before I even installed any add-ons. At the bottom of the screen, there's a 1-pixel tall strip that will show the color of whatever was last occupying that space. Example, if I drag a solid black-colored application over it, the area I dragged over will become black, and stay until I restart Pale Moon. In the attached image, the left-most area is grey because my left-positioned task bar comes out that far, but auto-hides, and the rest blue from my desktop.
This kind of problem isn't a big one, of course, but it's just annoying to look at. How/why could this be happening?http://s14.postimage.org/is26boxy8/Pale ... Glitch.jpg
