Hi Claudio Chen,
Sorry for the program error when pasting. It could be the clipboard data is too large to be pasted, or it could be corrupt preferences.
I'd try resetting the Photoshop preferences to see if that'll resolve the program error.
Let us know how that goes.
i have changed the memory allowance higher in the preference settings and it seems working now. i will keep updated to the problem to see whether it is solved.
the default setting limits the memory allowance for photoshop at about 3000-4000 MB. in ps cc 2016 version there is no such problem. now i rise it to about 5000 MB and it seems to be better.
thank you for you support!
Thanks for the update Chen, glad it's working for you.
Let us know if you run into further trouble,
