photoshop question

[Ni*]

not sure how i did it but i've got every brush in PS7 to show a chequered pattern on its edge when i draw a line. i tried resetting all the brushes but it still appears. its like i'm working with a texture on the brush but there's none. anyone got any suggestions?

thanks

edit, never mind i fixed it, can someone delete this please? me stoopid :-p
