Help making Red Dot sight

[Inurbelly]

Okay, so I'm trying to make a red dot sight for the B.A.R. that I have made and will soon be up for download. The red dot is dead center in Photoshop and I have the gun perfectly lined up with the red dot. But the problem is in the game, when I aim it is showing up as and oval and not a square like it should be, but when I shoot the dot becomes a square like it should be but is off center with the gun by 1 or 2 pixels... I don't know what the problem is, I've tried everything and I'm getting pretty frustrated with it.

Here are some pictures:

(The red lines are rulers that I can drag from the edges and they snap to the center of the image so I can see where the center is)

I think it is a bug, happens to me too. Just add another layer to the red dot, and it will look normal.

add one more layer of red to the left side, I have this glitch very often and that always fixes it

(Based on Windows 7 and my Windows Vista knowledge)

Go to, Start > All Programs > Ace of Spades, then click "Configuration." Open it up in notepad and change windowed = 0 to windowed = 1, make sure that the "x res" and "y res" are 800x600. Double-check that your sights are also 800x600, then in-game it should look perfect.

P.S The middle is actually in-between the 4 middle pixels.
