I can't take screen shots in OS X Lion:

[apple101]

Hi everyone,

I am having trouble taking screen shots in OS X Lion of the desktop. I have always taken them easily in Snow Leopard, but in Lion this dialog box comes up and following reads:

Your screen shots can't be saved.

You don't have permission to save files in the location where screen shots are stored.

------

This is the exact message what is being said. Does anybody know, what this is; or how to fix it?

Please help.

It seems like a permission problem, run disk utility and repair them.
