Window resizing in OS X??

Im sure many of you have noticed that the windows do not fit properly on the screen, like photobooth. When I have photobooth open, I can't see anything below the (SNAP) button, and when I press the green maximize button at the top, it doesn't fit to screen. Has anyone found a solution to this problem?

Thank you so much!

But be careful with the values. I use it only temporarily, just when really needed.

 

Its not working for me, I'm not sure if I am using it wrong, but why are there two boxes to input values? If I want it to be 0.85, how would I do that? Everytime I input 0.85 in the first box, it says Undefined

 

Nevermind, I figured it it's the password box and I had no password set, and if I don't have one set I get that error. So I had to set a user password.
