browser minimize button is gone

The minimize/maximize/close buttons on the top area of the browser in PS 7.0 is gone. How do I get it back?
(I can open and close the browser with the drop down menu from file but can't minimize it without the button)

The PS UI is kinda odd really ...

You have the browser docked in the Pallette Well. Click and hold on the tab and drag it onto the workspace. Then you'll be able to minimise, maximise and close it. If you want to put it back in the well, click on the pallette menu button [circle with right-facing triangle] and choose Dock to Pallette Well.
