I have no real experience troubleshooting this program and its errors, but have you updated your .NET Framework to 4.5?

Putting the image right off the bat so any confusion as to what I meant is gone. On the left is the brush tool with AntiAliasing off, and on the right is with it on. The mouse is pointed in the same spot, but only with AntiAliasing on does it draw in the center. I used the brush tool for 8-bit pixel art a lot in previous versions without ever encountering this problem. When trying to draw a circle with AA off, it's also really inaccurate and jumps all over the place. http://youtu.be/G1Rkd0CCZD0 Here is another example with AA off using a 10pt brush. This is not faked. Holding the mouse in this position draws the circle an entire pixel below and to the right of where I intended to draw. I encourage you to try the same thing and see the results for yourself. Edit: Fill types other than "Solid Color" are all Solid Color, as shown here: Tried this with both a transparent and non-transparent color as the secondary.
