This does not occur when using start + arrow keys to snap app windows.

I have a few apps arranged on my desktop just by manually moving them where I want. Skype for example, if you move torward the edge of the screen it will "snap" however on the left or right there is a noticable border (maybe 5 px?). Same thing happens with firefox. If I try to position it to a left/right edge, it moves away by about 5 px. Anyone else seeing this too?
