Restore default preferences
Preference settings control how Photoshop Elements displays images, cursors, and transparencies; saves files; uses plug‑ins and scratch disks, and so on. If the application exhibits unexpected behavior, the preferences file may be damaged. You can restore all preferences to their defaults.
Press and hold Option+Command+Shift immediately
after Photoshop Elements begins launching. Click Yes to delete the
Adobe Photoshop Elements settings file.
A new preferences file is created the next time you start Photoshop Elements. For information on a specific preference option, search for the preference name in Help.
