New Document dialog box question - Draw X8

Hello all.  Usually when starting a new document, a dialog would appear where I could select various page properties like size, color mode, etc.  I must have bumped a "do not show this again" button somewhere, as new documents now go straight to 12"x24" (the size of the engravable area on our old laser) without showing this dialog at all.

It isn't that big of a deal but if you know where I can enable that dialog box again, it'll save me a lot of clicks.

Thanks!
