Pixel Art

I made a tileable brick wall for an upcoming game, my problem is that when I import to flash and link it to another brick wall tile at 100% view it looks f*&$ed up lol. In photoshop there is no problem at all, I have tried putting the tile on exact coordinates(.0, .5) still gives me the same problem. here, take a look for yourselves…
