I believe I have found a bug on Photoshop CC 2014 with the Text Tool. I have already contacted Adobe Support, but here's how to reproduce it, just in case someone is getting the same problem
1- Open a PSD file with text layers. 2- Click on Image Menu, then select Duplicate. 3- Close the original file ( no the duplicated one ) 4- Try to modify those text layers on the duplicated file, ( color, font or even the text ) ... I end up getting an error box : " Could not complete your request because of a program error."
I could reproduce it on all my Macs running OS X 10.9.3 and Photoshop CC 2014. I can't deny I'm very disappointed with Adobe Customer Care, because took me more than 2 hours with the support, sending even video files reproducing the bug and trying to convince there's a problem with Photoshop CC 2014, and after all that time, I got a confirmation that there was a bug and a thank you very much message... Should be easier to report bugs to Adobe.
