Line tool in PS7

[FusionS2000]

I'm a newbie to photoshop and well something weird happened, I dont know how and when I did it but the line tool no longer just draws lines it makes like a rectangle thingy.
and I know I am not using the rectangle tool.
how do I fix it?

You probably have the width of the line set to be too wide...
