Photoshop CS6 Preferences [PIXELART]

[Zymf]

I USE PHOTOSHOP CS6 PORTABLE
I've been trying some pixel art recently and I've decided to use Photoshop - mainly because I find it's easy to use and has a lot of useful features.
As some of you may know, you can set up Photoshop for pixel art via it's preferences.
I've looked online and followed all the steps as to how to set up Photoshop for pixel art but my pencil tool always goes outside of the grid lines...

Also, when I zoom in/out the grid size changes?

Here's how I have Photoshop set up at the moment:

• 1px Gridline
• 1px Subdivision
• 1px Pencil size

I've tried changing the canvas size but that's not made any difference

I've worked it out anyway. Whenever I close Photoshop and open it again with the same preferences, the grid becomes slightly inaccurate - I just have to redo the preferences.

Thanks though
