Forgot to mention I have tried this on multiple machine and have the same problem.
Interestingly I have found that if I modify a document in CS6 from an earlier CS3-CS5 document and save it - it works fine. But if I create a new document in CS6 the issue persists.
Looks like I will be modifying old documents for the time being
Would be grateful for some advise eon this.
Have you installed the latest updates for photoshop cs6?
(Help>Updates from within photoshop cs6)
Thanks for your reply R_Kelly
I have installed all the updates available today and still no joy.
Try making a new document in photoshop cs6, as the others may be corrupted as far as the text layers are concerned.
Also, you might have to reset the photoshop cs6 preferences:
Yes I have been creating new documents every time.
I have reset all preferences on both CS3 and CS6 and reset all tools etc
Still no joy
