Resetting Photoshop CS Preferences

Oneof the best way to fix many common problems in Photoshop is to delete the Preferences. The easiest way to do this is while launching PhotoshopCS hold down Command–Option–Shift (PC: Control–Alt–Shift). You’ll be asked if you want to “delete the Adobe Photoshop Settings file.” Click OK and all your settings will revert back to the original, “out of the box” defaults.
