Why don't Photoshop shapes align to the pixel grid?


I have Photoshop CS3 on a Windows 7 32bit machine with onboard / integrated Q45/Q43 chipset graphics.

I have a problem where it seems any Photoshop element; shapes, text and the like do not align themselves properly to my 1px grid.

This is a screenshot. I am fully zoomed in on a square shape.

As you can see, it doesn't align properly.
If I try to use the transform controls to force it to align to the grid, this happens...

How can I get Photoshop to behave properly?

You appear to be using Photoshop CS3.

Photoshop CS3 has no awareness of the pixel grid. The pixel grid was introduced in later versions. If you need pixel perfect images you can disable anti-aliasing and / or use the pencil tool to manually edit pixels. There's no way to get things to snap to the pixel grid in CS3.
