Screen changes when cursor hits upper lefthand cornor

[420benz]

With a page open and i move up to close it,if the cursor hits the upper left hand corner a new page opens and it is all gray with a + in the lower left hand corner and an arrow in the lower right hand corner. If i click on the arrow a bunch of icons appear on the bottom. How to stop this.

I don't know if this is for real but I'm feeling tutorialy tonight ^^

You're looking at dashboard a special "space" where you can put widgets.

Dashboard preferences are in :

Lion :
System Preferences > Mission Control :
There you have "show dashboard as a space" (your case) otherwise dashboard appears as an overlay on your display (quite useful if you find widgets that you like).

Look for the "Hot Corners" button that shows you what action happen when you move the mouse cursor to one of the four screen corners (select "-" for all corners if you don't want anything special to happen).

The hot corners are quite useful to turn the screen saver on etc.

Thanks Torrijos. Hope you keep solving my DUMB questions.
