!!

Solved thanks everyone!:)
Hi,
I was  using PSPX when I accidentally clicked the maximize button on the window for the graphic that i was working on, which created a screen like this:

Which wouldn't  let me get back to the workspace that can hold many windows with different graphics like this:

My question is, how do I get it back to the a screen like picture #2 without having to exit the program and open it again?
Thanks in advance!
