I do have a problem all the time when I wanted to copy my graphs from Graphpad Prism into the Illustrator, it is saying that it cannot paste the graphs due to unknown error. And the same graphs can be copied and pasted nicely in other software like MS powerpoint. And i have already looked up the community and tried to follow whatever is described there but my desktop (window) seems to have a different folder direction and I am not able to fix this problem. With my previous MacPro I never had this issue, i do not know how to solve this. Can anyone have a solution for this?
