Brush Stroke Help....

Okay well I was trying to achieve a look in this one image I made again (behind cut) but when I do the stroke that I used is off by a pixel on the right and on the bottom. I have pictures and an explaination of what I did to see if that helps you help me.... so, HELP ME ;) lol.


What I'm trying to achieve again:

What happens (zoomed in):



What I do:

I made a white border then tried to make another dashed border inside... well what I do is I go to the "Rectangular Marquee Tool" and set it so that the border is symmetrical. Then I right click and choose "make work path" then after the work path is made I right click again and choose "stroke path" then set it to "brush"........ For the brush I make the angle jitter set to "direction" and all the other two options I've set to "off"

and when I use the regular "Rectangle Tool" to make just a normal path it gets worse when I fill the path with the brush. With my brush set the same, the brush vanishes on 2 sides (left and bottom).

So WHATs the Matter?

Thanks in Advance =D
