Photoshop: I can’t drag the paint brush!?

I have the 6.0 Version of Adobe Photoshop. And when I want to use the paint brush, I can’t drag it. If I do, It’ll only blend the little streak to the background color, and it’ll only be like, one inch long, and won’t go any further. Here’s a picture:


So I have to click repeatedly to cover an area. Do you know what is wrong? and how I can fix this so I CAN drag the paintbrush? And it’s not the version, because the downstair’s computer has the same version and that one drags. ='(
