Beryl crashed when I logged out

Binary package hint: beryl-core

I have always had this issue due to me being so new to Linux. I am constantly told I need a window manager in order to use Beryl or Compiz. Yet no one does into detail about this. Everytime I run Beryl, the "borders" of my open windows would disappear, whereas i could not move or resize them. I cant understand this as I thought the current window manager was appropriate enough.

How can I fix this issue?
