I know this is a ridiculous problem to have, but I have checked the manuals and can't find a thing on it. If I have a rectangular selection that I choose to modify, by expanding, or border, say, it takes what was a perfect corner and cuts it at a diagonal (stair-steps it). This is not really a video related question, as this is a portfolio for a designer, but I hope someone here knows how to get square corners when modifying, without going to manually fix each corner.
Expand grows out alogn the pixel path... so it rounds out (or stair steps)
Use Select>Transofrm Selection (just liek Free Transform) You can drag handles or specify size in options bar
