problem with texturing

[j-man]

It seems that when ever I try to apply a texture to my model, the texture wont stay   :help:

Here's what I do:

1.I select a face
2.I enter texture mode
3.I select the area I want to texture
4.I load my texture (which is a .pac image)
5.I press 'B'

My texture apears on the model, but when I exit texture mode, select another face, and enter texture mode again, I cant select another area to texture. When I drag the box around the area I want textured, my previous texture fills the box I just dragged. I hope this dosn't sound too confusing

Right click and load the texture you want.
