Are you pasting the code into the CMS Window in code View or in design View?
If you are posting it in design view, what does the code look like if you switch to code view?
What I discovered is that I have to remove all of the text formatting in Dreamweaver prior to copying or cutting and pasting into PowerCMS. If I take this approach the text will paste into PowerCMS with no formatting. At this point PowerCMS will allow me to add and or configure text as I want to. I don't know if this is a bug or if I'm simply doing something worng, I love the freedom that your CMS provides and have already purchased two licenses.
