I am having trouble reliably pasting from Publisher. Sometimes it works, other times (mostly) it doesn't. Sometimes if I keep playing with it, I can get something to paste, but it would be in the wrong place. I don't know how to move it, so I start over, only unable to get it to work again. Any suggestions?
Correct me if I am wrong here, but, it sounds like you are designing a print newsletter in Publisher, and you are trying to convert that to CC.
So, based on that concept, I answered the question.
Now, if you are just trying to take "content" from a Publisher document into a CC template - that is a different concept.
Publisher, like Word, formats the text, which really messes up you design. So, what I have always told folks is to copy from Publisher (or Word) and paste it into a "text editor" (Notepad, SubEthaEdit). This removes all the formatting. While I have it in Notepad, I check for "fancy quotes" and other "special characters" and convert them to HTML Entities. Then I copy the content from the text editor and paste that into my CC template.
