As you work with text layers in Adobe Photoshop CS6, the text is replaced by text from a different layer or randomly changes. Or, the text becomes corrupted.
Perform the following steps in order.
Important; read carefully:
Delete the Photoshop font cache.
Mac OS: Quit Photoshop, and delete the /Users/[user name]/Library/Caches/Adobe/TypeSupport/CS6 folder.
Note: If you're using Mac OS 10.7 or later, see this TechNote to open the Users/[user name]/Library folder.
Windows XP: Exit Photoshop and delete \Documents and Settings\Local Settings\Application Data\Adobe\TypeSupport\CS6\ folder.
Windows 7: Exit Photoshop and delete the \Users\AppData\Local\Adobe\TypeSupport\CS6\ folder.
