How do I turn off anti-aliasing in Windows 7 (Solved)

[A.J. Nitro]

It's actually different on 7, but lets ignore that problem for now.

Anyway, while we're on the subject of Paint, here's another yet more serious issue I'm having. Sometimes whenever I try to save an image in Paint, I often get this:

Whenever that happens, it deletes my work entirely leaving a completely blank image. Absolutely nothing! Nada! And no way of getting the complete image back, unless I select all and copy, but that won't always help me since this usually happens whenever I try to save. Is there anyway, of preventing this for future projects?
