Enable Document floating in Photoshop CS4.

Enable Document floating in Photoshop CS4.

In Photoshop CS4 if you open more than one file it will dock as tabs (Like firefox tabs) side by side [red bordered box in the image]. Therefore you can not view both files at a time. (which is very useful to drag and drop images from one file to another.) To enable this feature Go to Edit--> Preferences --> interface (shortcutkey Ctrl+k) and uncheck Open Documents as Tabs & enable floating document. [marked with blue color outline]
