Do i need to re-install Photoshop?




Does the problem only occur in Photoshop? If it occurs elsewhere leave PS alone and start checking your keyboard – a good blow-out with a compressed air spray can , or remove and re-seat the offending keys.

If it is only in PS, reset your preferences as described in the FAQ.

(You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.)

This resets all settings in Photoshop to factory defaults.

A complete uninstall/re-install will not affect the preferences and a corrupt file there may be causing the problem.
